SPI Discount code....  By  carasdad (Read 1,824 times)

Thanks for the tip Glenn javascript:%20addSmiley("%20:D") I am amazed that they sell the 50mm Air Sal so cheap as it is really high quality product , much better than the average junk and cheaper than the expensive Italian goodies .

Have you used that reed valve kit ? After reading Teddys post where his stock metal ones broke and he had pieces get into the engine I have worried about mine doing this . I removed mine to inspect the reeds and they felt very flexible for metal . I am debating on replacing them with CF reeds since most intakes are for the forward facing carb but mine is rear facing or type 2 . The stock intake seems to be small as the 19mm TK needs an adapter since the venturi is larger than it . I know it restricts airflow as it was intended to be a moped instead of a screamer . I could not get a 100% answer if I could use a Hoca or Stage6 intake as it looks like it would bolt up and I have plenty of room to move the carb as its wider and shorter tubing than the stock one . I put Boyseen ( spelled wrong ) FG reeds in my Honda CR125 that I build myself when I was 16 and it made throttle more responsive as I used jets so large that it would bog or zing throwing many off of it . I set it up for racing not trail riding .

Do you still have those Minarelli gears ? If so they slide out after removing the oil and cover plate behind the clutch ? Then they would need to be pressed on the shaft ? I have tinkered with small engines since I was a pup but never have I done a gear swap . What is weird it has never been quick on initial takeoff , but midrange its a beast and with the racing pipe I can hit 9k RPMs up a steep hill with a running start as when I hit 50 MPH with the pipe vs stock one , its like it goes into under drive as I only give it just past idle of throttle or it will hit 10,500 , so not fun downhill since I can not push it . I try not to go over 9k RPMs since the previous build a wristpin came out while I was redlining it and destroyed the piston , head and cylinder . I tugged on them good and double checked before sliding the new cylinder all the way down . I prefer to ride not push . I put in 1.5k clutch springs and went from 5g rollers to 8g sliders as I figured it would help lower the RPMs at top end , but it only hurt takeoff and up hill from a deadstop with the same under drive effect . With 5g rollers I could let off of the throttle then hit WOT and with a lil pull pop and ride a wheelie for a few feet as the power peak 7,500 to 9,500 . Better reeds and larger intake should improve the flow and response . The MODCycle kit is a beast to be one of the cheaper priced kits .

I know what you mean as some great threads often do not get many replies where some get pages of em

Before you call me rude again maybe you should reread you own post name calling and talking down about people you don't even know. Treat people how you want to be treated dude.

I bought one of your heads for a 50mm Airsal kit I had on a Peace Sports B09. Power increase was unreal!! Good looking head..nice work too..a Machine Shop would have charged me twice as much for the labor alone..

I've tested the heads made by buford its the way to go, good as it gets
