After a long sabbatical, I am looking to get back to road racing. I have always wanted a GP125 (or nowadays, the 4-stroke equivalent), but it looks like the GP125 class no longer exists. There used to be a small but loyal GP contingent in the southeast region with both 125 and 250 GP replicas. Are they still around? Is there another club with a GP125 class?
AHRMA seems to get the largest two-stroke grids these days. RRR in February and CMP in March would be closest for you.
Fester! 125's are slowly disappearing. Either a 125 two stroke the 250 equivalent are going to be expensive. Most 125's I have seen recently don't have much spares as far as consumables. Maybe some gearing, used parts, and stands....Its not like it use to be! you just missed a decent one too https://forums.13x.com/index.php?threads/1996-honda-rs125r.391582/
Yup, I don't see very many 2-strokes on the grid. I'm usually the only one. Last year I was fighting some squish problems and didn't get mine out there, but i'll have the TZ250 out there this coming season
Well, I'm just looking to have fun, and it looks like the NSF250R (or an RS125) is ok in Clubman, F2, and more. So I guess I'll just get a bike I like and help Stickboy and WERA pay some bills (if nothing else).
Having wrenched on both my sons RS125 and Moriwaki, which is a much slower version of the NSF250R, I think I would choose a 4 stroke. After 3 years I was tired of checking the ring lands for compression and jetting and needles, and new pistons every weekend or two, plus the occasional crank. Having said that I don’t know the maintenance schedule on a NSF, but even our hotrod (250R instead of X with ported head and cams) Moriwaki required much less maintenance.
I don't disagree. When you are racing pretty competitively that means the top end is coming off every Friday/Saturday tpo be looked at, at the track, plus all the carb tuning. I love 2 strokes too, and at my much less competitive pace it would be less of a problem, but when you are running against other kids who have dads that blew 100K on a bike it was a lot of work. I just honestly got tired of all the wrenching and expense. 600's club tire expense seemed to cost about the same as a 125 tire and consumables expense, when you get all the pistons/rings/cranks, etc. into the mix.
I pulled my every three race weekends at best. No seizures or issues but I had mine pretty figured out with jetting, temp setting, gearing, etc. I did however pull the clutch prior to every race and clean the steels so I could get a good start off the line. Any blueing and they always grabbed to much…
