that is weird, because all the first thumb is is a .jpg...no reason i can think of you'd see only part of it.
Thanks for some experienced information! However, I understand these Chinese two-strokes to have a lower static compression ratio and that they do not need high octane fuel. Also, E15 is not available everywhere.LiamSckhot
Been building The sched 40 pvc boost bottles since 2005 [and have had] good results on Grubee 48cc roundhead: Better low end. I live in mountains. First bike did 44 mph on flat no tailwind. Boost bottle is for low end only... maybe 4 to 6 mph on top speed. 3 and 3\4 inch of sched 40 1 inch and two end caps = just under 48cc. Slight tilt down for fuel drain.
Been breaking [it] in... my bikes rich and then move into a tech mod green neet fuel formula with right stuff. Start out with E15 93 octane add TOPSHELF t2 best you can afford , leave room for special additaves and catalyst and octane booster gets up to about 106 octane can go higher.
The stuff I has been around fovever just like caster oil with a small % of nitro for race bikes. Caster oil is same as bio or veg oil but mixes properly same as vintage T2 race mix. Have not gone too high octane do not want to mess with time settings.
Have cleaned flashing out of ports , no re -porting. Use stock exhaust with extra hole drilled in end of pipe about 1\4 inch hole helps de-stress these funny little pipes on Chinese Grubee engines. I say you need graduated mix tube for extremely accurate mix critical factor.
Hi quarkdude, its me Keith. Ive joined in. You guys have some great things to say and some really great ideas. I spoke with Augiedog earlier. You guys seam like a real close net and I think I could learn a few things from you guys. I spoke with thatdax.com and we are trying to work out something on the intakes as we speak. If i can purchase them from him then I will. We will pretap the intakes and offer them on our site. Although the metal intakes seam to be a popular item it maybe that the aluminum offer more meat for us to thread. If this is the case we may want to go with the aluminum intake. Any help finding other suppliers is appreciated. Also tell your friends, send pics.Hello Large Filipino,
I am going to send an email to Keith also and mention MBc, send him the link, and send him pictures of my Boost Bottle install again. Maybe a simple aluminum spacer between the stock 80cc Chinese intake manifold and the cylinder head could be made cheap to allow the NPT nipple to be installed into spacer and be a bolt on kit like you mentioned. Might have air cleaner cover space issues but maybe it would work.
