Ho guys names anth i have a typhoon 172 stock 52mm race crank 24mm inlet 25mm delly carb 105 jet 50 pilot needle 2nd clip from top needle d22 stage 6 reedblock and reeds transmission stock driver stock contra stock new original clutch and springs new oem belt malossi variator 12.5g rollers original stock runner pipe my issue is pull Off Is horrible midrange flat like no power but crawls upto 60mph tried swapping contra for malossi white and back and forth with stock contra with rollers from 11.5g to 12g to 12.5g to 13.5g no difference u sure if jet might be to big for stock pipe bit running 39mm pedmoto open sponge filter aswel any help and advice would be massively appreciated as dont need heavy mechanic bills For something what may be simple Fix for the right person cheers
I would try lighter rollers , sounds like you are getting into "high gear" too early also the stock runner pipe will be strangling the other mods , jet sounds about right.
How light mate i always believed the stock runner pipes where good on a typh always believed had to go lighter with a sports pipe? Also mate the airscrew how many turns should that actually be as a base guidliNe also put stock reedblock in now still no difference did have pd pipe on there but was way to loud so threw it on runner 172
I`d try 7.5 g and go from there , probably buying a set of several different weights be best way to go , say 7.5/8.5/and 9.5 then you can mix and match , i always turn air screw right in then out 1 1/2 turns and go from there 101 octane are a decent cheap roller for setting up then when right swop out for a top end brand
7.5g rollers for a 172cc aint them Sizes like not far off a 70 to 80cc bike or 100cc never known a runner 172 to ever be below a 9g setup?? My clutch bell is blue with shades of purple in aswel could be warped off heat which might be making clutch clip
