Mini moto advise required to race on TMGP.

I am interested in start racing mini motard at TMGP specifically at GCKI track. I have a CR85 that I was thinking to convert to a motard but now reading the rules at TMGP website I can only run in Unlimited class (I donít know how fun is this class) and I canít do any endurance race so I am thinking to sell my CR85 and get a 65 size bike. I would like to stay in the 2 strokes world but any other bike suggestion will be considered. I have been trying to contact TMGP staff to get some info but I havenít had luck getting and answer back. What bike, based in your experience would you recommend to me. I am 6í-2Ē tall and 220 pounds. I am in between the Kawa KX65, KTM 65 SX or Kawa KLX 110 4 strokes. Can you run the KTM 65SX with the stock front brakes?. Any help/orientation would be appreciated.
Thanks.

Sleeve it down to 72cc, you are going to be uncomfortable on a 65.

If I sleeve it down to 72cc. Would it be legal to race?. I was reading on the rules that for 2 strokes water cooled the maximun engine size is 65cc. Am I wrong?

an 85 can run in unlimited & motard in sprints but no endurance class

if you want to stick with the bike you have I would do what jason suggested and sleeve it down to a 72 as most kx/rm65 out there are bored to a 72. Couple yrs ago we use to have a team that enduranced an 85 that was sleeved down to a 72 and were quite competive.

There are a couple other options if you want to change but stay on a larger chassis, you can stick a xr/crf100 motor in your current cr chassis, which is quite common. You can also switch completely to the xr/cff 100 and there is also the ttr125.

Concerning getting ahold of tmgp staff, have you tried the "new riders" link on http://www.tmgps.8k.com/ ? The # there should be good, if not shoot me a pm and I will try to help ya out

I wouldnít like to bore down my CR85. Based in your advisees I guess I will have to switch completely and forget my lovely 2 strokes bikes. Will the ttr125 allowed to race endurance class and spring class?. What is the maximun engine size on 4 strokes for endurance and Spring class?

I have Jason's old KX 65 which has been great to me until first race this year *complete engine build later* the KTM65's brakes are better stock then the kx's.

It depends on how many races you want to run per day if you want to run like 12 or 14 races per weekend and ironman it you can do like rob said and do the xr100 motor but will be slower. If you only plan on sprinting 4 or 5 sprints per weekend then a KX65/KTM65/RM65 bored out to a 72cc is the way to go like mine

I am not planning to run a whole lot of races per weekend. I am planning to race a few but I would love to enjoy the 2 strokes driving and have fun. My main concern on the 65 is being uncomfortable in the chassis but I don't know if to run a few races on the weekend it would be fine. How much will cost to bore a 65cc to 72cc. Will a stock 65cc be too slow?

the KX65 is not that hard to ride. most of us who have 1 are around 5'8"-6' they are comfortable to ride. I have rode a 85 frame though which was a cadillac compared to the kx65 on the endurance race but id never sell my 65.

there are 2 guys who have stock or claim to be stock 65's and they are still hella fast i'm not sure if they are true 65's like they claim or just weigh 120lb's lol

I feel comfortable on my 85, when I was in the 65 at the bike shop I felt it a bit tide and also the suspension on the 65 is way to soft for my weight. I will go to wildwest to try the 65 again and see how tide I am in the bike. When I choose what bike to go with I will ask for advise on how to modify the suspension.

If you decide on an XR100, I may consider parting with mine (its pretty well sorted out). I have been toying with the idea of building a CRF150 for the track days over here in NOLA.

well if you want a bigger chassis and stay 2 stroke your options are limited. the ttr125 is a f6 bike and can run several sprints aswell as endurance but its not a very competive bike due to it being under powered compared to other f6 bikes

you can get hd spokes from http://www.buchananspokes.com/ and wheels from http://www.radmfg.com/

depending it you want 12's or 17's will dictate cost

So stock hubs? 17s would prob be the better option I assume. I have seen some 12s online i like the looks of them.What do ypu think it would cost to lace the wheels up?

yeah lacing to the stock hubs, thatís what most of us do but the only down side is you wonít have the option to throw dirt tires on unless you buy another set of wheels. If you donít know how to lace them or know a friend that can help you, honestly I would touch base with chad(magicman) he can lace and true them for you and if you need help finding spokes & hoops chad can also help you there too.

as far as 12's vs. 17's itís more a of a personal preference and where youíre going to be riding the bike the most. i have ridden xr100's with a 12 inch setup and a 17 inch setup, both have their advantages and disadvantages

as far as suspension for the KX/RM 65's i have a super cheap easy way for you to mod it if you got a little time. i raced all last year on a 07 GSXR 600 rear shock i modded the kx65 to make it work i have 3 of the shocks sitting in the garage. then put heavier springs and race tech gold valves in the front forks and your done.

or you could do the expensive route like some of us and buy a Ohlins rear shock and setup properly for the bike but it cost me $$$$$ to do it but its night and day difference.
