Just got a King Sand Car with a Hayabusa engine and I'm having trouble taking off from a dead stop. Some times it all goes well and seems normal and other times it seems like I have to really rev it and super feather the clutch?? I stall it on take off about 30-50% of the time.   rofl Don't feel bad,I do it all the time. ;)

I also feel it's too high geared I spend most of my time in the dunes in second gear third seems to either be way too fast or bogs out real easy. Is this normal for the busa cars? I'd love to be able to take off easier and use more of the gears is there a way to lower the gears down somehow?

I have a 14 tooth front sprocket and I don't have any room in the rear to go bigger on the rear sprocket. There us a 13 tooth front available. What is your rear count?

I'm looking at doing a Tom Pro reverse (unless there is a better option) which has a 1.38 to one gear reduction built in. I'm not sure what that means or how much of a difference it will make??? It will reduce your overall ratio by approximately 1/3.
nyone have any recommendations for me? I love this car but I'd like to make it more useable!!!

what size tires are you running? what does the rail weigh? what is the rear sprocket tooth count? a 13 tooth counter shaft sprocket does work fine on those engines.

Ok first one I'm working on is a gen 2 engine it has a 14 tooth front sprocket and the biggest rear sprocket I can possibly fit!

Rail weighs about 1600-1800 with passengers I'm told - not completely sure

Tires measure about 30-31" tall including paddles

Are there secrets to these clutches I've read that even the street bike guys complain that they feel different every launch!

What do I need to build the best possible sand rail clutch for this engine?

I'm still running the same clutch since I built my busa car several years ago. Lots and lots of miles on it. Mine weighs over 1800#'s with dune tires. Stock frictions are ,IMO and many others,the best out there. Add HD clutch springs,possibly modify or replace back torque limiter(I still have the back torque limiter in mine). Some feel a billet ckutch basket is mandatory yet I'm still running the stock basket.It may fail tomorrow but...............  Clutch should be the least of your worries.

http://www.hayabusazone.com/clutch.html

Trac king clutch plates/discs
super heavy clutch spring kit
clutch cover support (must do this with the springs)

This is what I run in mine and the only thing that has lasted.

Stupid question but you're sure your starting out in first gear?  It is a bike and first gear is in a different direction than all the other gears.....

We need a tooth count on the rear sprocket.

We assume you are using a 530 chain. Is that correct?

this is an excellent question.....many in the past believed the 630 chain was the strongest however several 530 chain manufacturers like ek zzz 530 x ring or o ring chains have are as strong if not a tad stronger than 630. going 530 allows you to go a few teeth larger on rear as well.  i ran a 14/70 ratio on my turbo busa rail with 30" sand viper paddles 1100's. my rail was 1300 lbs ....absolutely need a clutch slave saver and order a back tq eliminator from schnitz racing along with there good clutch and stronger clutch springs. i know fabr still has his but he has a gear box. on my sprocket drive rail that back tq limiter made dead stop take offs jerky in mine. cheap and easy to replace while changing clutch.

i do believe a stock clutch would be just fine as well with stronger springs and a slave saver is a must. make sure you use the proper oil for the bike engine as well as it is a wet clutch so a friction modifier is required in the oil. that back tq limiter makes the take off choppy or shaky and can diminish the take off. my rule of thumb always was 13/62 or 64 at around 800 lb to 900 lb using blaster 26 paddles. the 15" rims with 1100 paddles require a deeper gearing. stu makes a blaster 28 paddle but only fits 14" rim. much better tire than the 1100 and prob 8 to 10 lbs lighter per tire. if your running the 1100 paddles then you'll prob want to be 13/70 or 14/70 min.  counter shaft sprocket/rear sprocket.

IF you need a custom rear sprocket made that'll last a few years not a few rides let me know.
