that is a very nice build you've got going there.

The way i see it is if we are going to be catching up to the SCTA rule book then we should follow there rule, as of jan 1 2011 all new cars and motorcycle stremliners must have an SFI 38.1 head and neck restraint system. Not just a Hans but any one of the systems as long as it meets SFI 38.1 The rul...

you need to read the rule book very carefully because in the seat belt section it says to mount the harness as close to the seat as possible, the harness bar is best to go across the main hoop and not between the rear stays.

its all there in black and white. All G,H.I,J and K (.50 l to 2.00 l) engine classes where existing record is under 175 mph may use a tubing size of no less than 1.5" od X 0.095""wall thickness. The roll cage its self min 4 point with a taxi bar and diagonal.

Sweet looking ride jnr, love the cafe style tail on it. All the best for the big white dyno.

nice to see you back on here bob

Lad Waggon, will the bike pull redline in top woth the stock gearing ? What internal ratio is top gear (including primary reduction) beware of overdrive top , gear for the gear closest to 1 /1 to be the gear you use, and aim for getting revs as close to maximum horsepower range, in an ideal situati...

Thanks to everyone for your help. I've been loooking on the web and have found some interesting things. I'm going to keep the stock ratio and buy a 1 down for the rear to try on the dyno, and see if it can pull in top with that.

lag waggon.. 1 tooth on the rear is about 400 RPM it won't pull in top and 1 tooth on the front is about 4 off the rear,, I've googled gear ratio's in the past and you can find heaps of info...and spread sheets.. Thanks Dirtydave, i have a gearing program and it says 1 on the front is worth 3 off t...

Thanks rob, ill have to buy 4 new sprokets cause the 16 i want is 520 and my old is 525. Looking at the ratios, those 4 give a good range for change, but is going from 3:1 - 269:1 ok ? not to bigger drop?

Ok i am going to change my sprokets but im not to sure how far i can go. I've got 15 45t standard and ive done some looking and i can get a 16t front but just not sure what i should do on the back, i think a 43. It's only a 600cc 4 banger sport bike lump, and i dont want to load it up to much. Any h...

How about the 7th? as its a sunday, might be better incase poeple are working saturday. Either day suits me anyhow
