any one fitted throttle cam system

gearing

but wouldnt putting a 14 on front hav same affect as you are making top end faster and aceleration slower ?

I would definitely try either 13/50 or better yet 13/49. I don't think you'll be disappointed. Also, my bike was stalling at crawling speeds if I just tapped the rear brake and one thing that really helped was turning up the idle adjustment screw a little. Now I can really crawl around.

I have a G2 cam (least aggressive one they offer) on my 04 TC450. It helped me be able to modulate the throttle better at low speeds. The guy that runs the company is very helpful and will swap cams if you want to try a different one.

Good luck

My G2 came with 3 cams, a 100, 200 and 400. I'm using the slowest rate ,400, and stock gearing (13/47). I've come to realize I'm not using the clutch enough at slow speeds in the tight stuff and am also finding out I've got better luck not slowing down as much and just go for it. Not saying that's your problem but the less I try to lug it and chance the"POP!" and dive the less I end up picking up the bike And it somehow seems to get heavier at the end of the day Hope that made sense.

yep

yes guys i hav a 50 supersprox in the garage from my beta/going to give that a wirl and maybe throttle cam dont think 49 is going to make great difference to a 50,just a locall racekeep you team chap had 510 and put on a 14 and it helped and another chap from husky sport uk said the same but for what i do i surely dont need any more top end/but putting on 14 would i think make bottem end slower or make gears slighlty longer.keep you informed

14 front

fitted 14 front sprocket bike doesnt rev as much and seems to hav lot more low down grunt,allso fitted g2 yet to try that ,out on sun so will keep you informed.

I don't see how going from a 13 to a 14 would help in "rocky/tight snotty trails". For the same amount of throttle, the tire will spin more. I'm sure it felt different, but not sure it would help.

It would help if the bike was over geared, never using first gear etc. Would make all gears more user friendly, less chance of breaking tire contact. But if its already geared perfectly, then first would be lugging, stalling, & lots of clutch use.
Depends a lot on the bike, (little 250 or big 510) the low end characteristics, the rider etc. It's a little like setting suspension up for yourself, your weight & riding style. Every one is a little bit different in what characteristic's they want & need. Playing with C\S sprockets is a cheap way to find ideal gear ratio's for your needs

sprocket

wont spin more it will spin less,one on front is like dropping 3 on back more top end less bottom,and the 08s are not geared right at all in my opinion and the opinion of severall friends?

patgas, if you increase from 13 to 14 then the tire spins more for each complete turn of the countershaft.

Like Ruffus said, though, how it affects each of us is likely different. For me, having the wheel spin slower at slow speeds reduced how much my bike lurched forward with the twist of the throttle. It did, however, make the tire hook up more easily and allow the front end come up more easily and made the bike feel faster. Lowering the gearing made my drz much much better offroad at slow speeds and much worse at highway speeds. For my 08TE250, I am at stock 13/50 and it feels perfect where/how I ride. Like Ruffus said though, C/S sprockets are cheap so I'd also get a 12 and see what you think. If I ended up liking the 12, I'd probably go back to 13 and raise the back to 49 or 50. I'm sure you can find something that works well for you in your riding conditions.

i run 14 x 52 gearing i ride it in the bush ,thats where i want my action to be and its great , not much good on the road though but i didnt buy the bike for the road . i have the G2 throtle cam AND ITS GREAT I RUN THE k400 cam gets rid of the low down bottom hit , makes standing ,tight single track , and mx so much better more control over the throttle i also have the recluse pro as well . yep it's so easy to ride and control ,thats how i like it , point it and shoot

If it takes the chain moving 47 links to rotate the tire once, then a rear sprocket that has 50 links will take more chain links being moved to rotate it once. It's easier to illustrate by imagining how many chain links need to move if the front was 13 and the rear sprocket had only 13 links. One rotation of the front would be one rotation of the back. If then you put a 52 on the back, then one rotation of the front would mean 1/4 rotation of the back or 4 rotations of the front would mean one rotation of the rear. So, bigger in the front or smaller in the back means more tire rotation for the same number of countershaft turns. Smaller in the front or larger in the back means less tire rotation for the same number of countershaft turns.

Higher gearing means more speed and wheel spin. Lower gearing means more torque, but not more speed or wheel spin. However, lower gearing may result in the rider going faster. That all depends on the rider and terrain, right?

yipeeeeeeeeeeeee

14 front and throttle cam rocks,husky uk where right,bike doesnt rev as much lot more low down grunt less wheel spin,more traction,longer gears forget 12 front sprocket go 14.maybe try 48 49 on back in future awsome .hav to disagree guys

Glad to hear you've found something you like. If you do try a 49 on the back, let me know if it feels the same as it did when you were 13/47 because it should be darn close. BTW, if it's interesting here's a good gear ratio chart.
