  1. New mark 3, new coilovers & spring rates?

    in Chassis

    Posted

    So I’ve owned my Robin Hood new mark3 for a year now, the rears already have Gaz shocks, the front are still the standard originals with the red springs & zimmeride shocks I believe? 
     

    I'm wanting to upgrade at least to some new shocks, either gaz or protech? What would be my best option, new shocks with original springs? Or complete new units with springs? 
     

    if so does anyone know what spring rate to go for on the new mark 3 with outboard coilovers?  
     

    can’t find much info on these models so any help is much appreciated!

    Decent shocks (all round) with reduced spring rates, tie bar modification and a good set-up should see you most of the way there*

    Plethora of info is there if you have a search and good read. As a starter have a look at older posts from Jim Stott, Longboarder, Mowerman etc.. they will give the specifics.
     

    *Assuming you have decent tyres and running them at reasonable pressures

     

    Ok mate thanks, is there a way to work out what spring rate to go for? Or does everyone just go for 120ib ish? 
     

    also any other makes other than gaz to look for?

    Saw your post on the FB group - loads of good people with great intentions, but often comment without any great knowledge of the cars (does not apply to everyone!)

    There’s loads of info on the site about improvements that can be made to the earlier monocoque cars - start with a search for ‘series 3 suspension’, which should get you started.

    Perfect thanks mate, I’ll have a search through, tried to post some photos of mine but file size was too big!

    So I understand there is very little information on the mark 3s and even less parts for them. 
     

    I’ve only owned mine 3 months, does anyone have any information on potential front suspension upgrades? It’s the new mark 3 model with outboard coilovers! 
     

    The coilovers are standard with red springs, I believe they came with the Robin kit originally? And the rears have been upgraded to gaz!

     

    Edit - I’ve recently discovered about a tie bar conversion, is this easy to do? Would anyone be selling the parts needed to do this? 
     

    any help is much appreciated 

  8. Running on 2 cylinders with bike carbs, 2.0 pinto - advice needed.

    Personally I would do away with the vacuum advance on the dizzy, it’s only there really to improve fuel consumption, sounds like there are lots of possibilities for leaks, just leave one line for the servo. What fuel pump are you using, have you got a pressure regulator? 
    Sounds like possibly carbs 3&4 are just flooding, are the needle valves ok in them?


    I’m using a genuine zx6r electric fuel pump, think it’s max 3psi, I’m not using a regulator no, which needle valves do I need to check? I’ve just started stripping the carbs down

    I have a 2ltr pinto on Yamaha R1 carbs. The vacuum dizzy is connected to the carbs via tube only. 1 to each cylinder and 1 for brake servo. All "T"d into 1 tube to the dizzy. No chamber at all. Pressure regulator set at 1.5psi. everything works fine throughout the rev range. I would think it's a carb problem on the lines of Peter Bells suggestions.

    This is exactly how mines set up, might need to strip the carbs down I think

    Hello all, 

     

    so I’m after some desperate advice with some bike carbs on my 2.0 pinto, I’m running a vacuum dizzy with 1 vacuum outlet per manifold tube on the carbs and then the brake servo also on the 4th tube, these are all connected via t pieces and 6mm tube. 
     

    the problem I’ve got is it only seems to run on 2 cylinders, I know this is a carb / vacuum issue as I’ve swapped back to the original 32/36 carb and it runs a treat. 
     

    Any ideas what could be causing this? It’s only on cyl 3&4, if you rev the car above 3k then it seems to run normal / better, it’s only on low revs / idle.

    also if I disconnect the vacuum pipe from 3&4 on the manifold then it runs much better. 
     

    Could it be because I haven’t got a proper vacuum chamber and I’m only using 6mm pipe?

    Could the carbs be faulty?

    Could I have an air / vacuum leak?
     

    any help is much appreciated!

    Hi all!

     

    hope this is okay to post here, I was unable to post on events!

     

    Just wondering if anyone would be up for meeting & joining us at a car show next Saturday 1st July, it’s in Norfolk - Gt Yarmouth, would be great to meet & drive over with some others!

     

    so far there is 3 of us going, please let me know if you’d like to come too!

  12. Bike carbs with crank case & oil cap breather?

    in Engine

    Posted

    What’s everyone done with their breathers when fitting bike carbs? 
     

    hearing mixed options on just venting the crankcase to atmosphere and putting a little pod filter on the filler cap but then some people route both to a catch can, thoughts?

     

    ideally I’d prefer not to have a catch can to keep the engine bay tidier! But don’t want to cause any issues, any help is much appreciated!

    Does your mk3 have inboard or outboard front coilovers? If inboard it may well have the original springs which are much too firm. Its usual to change then to 130 lb. My original ones were red. Maybe post a picture of them? Also does it have the original Sierra anti roll bar connecting both sides of the front suspension. Top of the list is to change to tie rods. Lots of discussions on here will explain how to do it. It transforms the ride and handling. 

    If yours has the later mk3 with outboard coilovers then I'm afraid I cant help.

    Thanks for the response, yes mine is the later mk3 with outboard coilovers and they are red springs, I need to check if mine has the original anti roll bar, do you have a photo of what I’m looking for? 
     

    also do you know anything about seat dimensions and what options I have? 

  16. Suspension & Seat upgrade options for Robin Mark 3 New

    in Chassis

    Posted

    Hi all,

     

    Ive not long had my Robin and im still learning lots about them, two of the first  things im looking to sort are any suspension upgrades to improve ride comfort and to swap out the seats, the seats are mega uncomfortable and dig into your legs ( it looks like there's room to fit wider seats)

     

    Im thinking better shocks all round is a good place to start, does anyone have ideas what shocks i can fit, front & rear? 

    and the next question is does any one know what seats i could fit in the Robin?

    Any help is much appreciated

    Assuming that a standard webber DGAV carb fitted then this is what is fitted to mine.

    https://www.ebay.co.uk/itm/151465213776?var=0&mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338343596&toolid=10001&customid=eb%3Ag%3Avms%3Aeb%3Ap%3A151465213776%3BEAIaIQobChMIls2i6qPi-QIVCJftCh3Leg8MEAQYECABEgKcePD_BwE&gclid=EAIaIQobChMIls2i6qPi-QIVCJftCh3Leg8MEAQYECABEgKcePD_BwE

    Oil filter is just a standard 1983 Sierra 2l fitment available at any motor factors.

    Pintos like 20W50 oil, modern light oils do not always work.

    Gaskets go to motor factor or ebay.

    Thanks for the response! I’ve spotted that the steering column is touching the alternator, is there a fix for this?

    There were several versions of "standard" 2.0 pintos - carb. or injection, high and low compression etc.  What you can do with them depends on what you're starting off with.  Generally speaking, some work on the head and a camshaft change should get you towards 150hp, after that it's probably more economical to swap it for something more modern.

    There were also quite a few models of Robin Hood which are significantly different (monocoque or tubular chassis for example).  You'll find there are lots of improvements listed on here for the various types, as long as you know what sort you're buying.

    Hope this helps,  Steve

    Thanks for the response Steve! Generally speaking what sort of carbs fit the 2.0 pinto would you know? Possibly looking to go down the bike carb route but again, not sure where to start! Or would throttle bodies be a better shout? 

  23. Initial upgrades on a 2.0 pinto! First time owner!

    in Engine

    Posted

    So I’m going to look at / buy a 2008 Robin Hood with a 2.0 pinto engine, it’s all standard and no mods yet… 

     

    I’ve never owned a kit car before, I do work in the trade along with my dad who has recently built an SDR V-Storm!

     

    what are some initial mods / upgrades I can do / look into to get some more BHP out of these engines?

     

    also are there any other mods to consider looking into that aren’t engine related? I know nothing about these cars so any tips / advice is much appreciated! 
     

    looking forward to driving and working on one!
