Hey all along time ago i added 22 inch tires on the rear and it was pretty bad for how much speed i lost so i went to a 15 tooth front...still not the same i then modified my endcap and that gave me a nice bit more...then went up a tooth on the rear sprocket added a yoshi pipe, 172.5 main, airbox snorkles outside of box along frame and can still not pull the rev limiter like it did stock. I had my modified air box lid on during my speed runs and then took it off, put the stock 1 back on and moved the tubes out from under the gas tank and that gained a tiny bit more top speed. I no i can pull higher top speeds than i did stock...i pulled 73mph stock and am now doing 77-78 mph on the gps. Any ideas on the carb set up that might be a tad bit wrong. The air fuel mixture screw is 3.5 turns out im running a 172.5 main with a yoshi pipe, stock airbox with snorkles outside and 1 clip leaner than stock on the needle. Would a aftermarket carb, ported intake, and new rev limiter...for what it helps, help me pull top speed better?

 

A carb makes a big difference. I just added a TM45 mikuni to my DS and it is much fast then the stock carb.

 

Faster everywhere?... im really wanting more top end power. Is that carb easy to jet and set up?

 

from what i have read on here the lectron carbs are great for dialing in that good top end you want. the tm45 is very appealing to me because i hear that is a great trail carb. i hardly get past third. check the whats in your garage thread. there are some guys with aftermarket carbs in their garages.[img]i/expressions/face-icon-small-wink.gif[/img]
