I bought a 1990 Suzuki LT500R quad bike earlier this year and made quite a few mods to it

Managed a few outings and races on it but it needs a bit more poke IMO.

Looking to get it ported and played with for a few extra HP

Does anyone have any recomendations for a good UK based 2 stroke tuner?

stan stevens at brands hatch.

Stan Stevens is well known but how good are they? do they take their time or are they just a money making set up?

stan stephens best 2 stroke guru out there loves your bikes as much as you do turned my aprillia rs 250 into a killing machine

Markb_s1

very very very good IMO.

I think they do give higher priority to their race customers thought to be honest... I get a similar impression from what I've heard abotu HT racing.

This guy certainly knows his two strokes , took my old kx 250 to him an it flew afterwards...

not seen a lt500 for years my dad used to do beach races on em. what races you doing on it?? i used to race quads for a few years great fun but bloody knackering.
other ones worth noting
frank wrathall of dynojet uk

Give Mark Dent a call @ performancefab:

http://performancefab.co.uk

He will do do everything from hand porting the barrels to fabricating pipes....he even has his own dyno as well!

His own ~150Bhp RG500 has been legendry in the two stroke world for years....

Did a nice job of building My RG500 engine as well

stan stephens is your man he rebuilds my engines once a month to my spec and he can get the most out of your engine just talk to him over the phone ie, what racing you do,how you use the power etc he will sort you out

Just a bit of background on the engine at the moment

I've stipped and rebuilt the carb inc rejetting and recently added an FMF pipe, filter, and V force 3 reeds as well as porting the inlet boot to suit and its still not what I'd expect from this sort of thing, maybe I'm to used to fast cars

Its recently had a full rebuild with a 540 piston, only done about two hours ish now by the previous owner by Boretech

Planing to run a 34mm Lectron flat slide carb on 116 oct fuel and get some serious porting done to the barrel I reckon

Also looking to get an aftermarket billet head with interchangeable domes to adjust the squish and compression

Dont fancy porting it myself incase I fuck it up as you cant get the OEM parts any more

Stan Stevens is looking promising for the port and rebuild

AustenW

Mainly using the bike for fun, but try and have ago at beach, oval and MX

I used to have a Suzuki LT250 then a Yamaha Banshee over 16 years ago which I had breathed on which seemed alot quicker looking back but I was alot younger then

at the end of the day mate it a old motor 1990 . all so have you had a play with the gearing as theres a lot to be had from it . and all so wot are you wonting from the motor / top end / snap out of the courners ?????????

AustenW

Bit more kick up the arse and white knuckles accelorating out the bends is needed

Not tried gearing but it feels pretty good through the range as it is for what I'm doing

For an old motor there still the fastest most powerfull production quad ever made to date

have a go with the gearing first trust me i was a 125/250 and 500 AMCA exspert i won the satday at weston beach race in 1998 and then went onto sidecar motocross top 6 AMCA and top 30 ACU . Trust me your motor has more to give with the right gearing on it . go up 1 tuth on the rear and you will get a lot more snap out of the corners drop a tuth and you will loos the corner snapt but when the motor gets going you will have more top end dont do the front till you go 3 teath on the rear as thats a big step give it a go. all so when you put a after markit pipe on you will loos bottom end on the motor as they are done for mid and top power so thats why its time to play with the gearing....All the best

Nice bikes

You guys are propper mad to stand up on those things

I'll have to get some sprokets and have a play, would still like to get it ported and a bigger carb though

Might also look at the timing on the thing as it has never been checked, not sure if it can be adjusted or not

It also has an adjustable powervalve on the exhaust port so need to have a good play with that and make sure it is working properly

Previous owner had the rebuild done by boretech i recollect so unsure of what has or hasn't been done as I havent had the engine to pieces properly to have a look

Its done about 2 hours since rebuild with alot of new parts so should be working fine

One last thing if you do a beach race get your jetting right and dont just keep it flat out all the way as thats when a 2 stroke will go BANG

HAVE FUN MATE

AustenW

I ran it rich at the last meet which might be half the problem why it wasn't as snappy as I'd of expected

I was worried about blowing it up

Thanks for your help

Try giving Ian a ring here........http://www.iane.co.uk/

try DEP exhausts..derek elwell i think his name is..01622 765353....just say steve clitheroe (sct tuning)recommended them.

cheers Doug

AustenW

Any other pipe manufacturers?

cozzymatt

NRP exhausts, cant remember wether thay are in sheffield or chesterfield though...?
as said above, change the gearing on the rear, I had a tweeked Banshee and the difference the gearing made was fookin unreal out of the corners

Dannn

I can recommend both of these companies:
