We make a combination reed valve and crankcase stuffer kit that will improve performance and protect your motor from broken steel reed sadness,available with necessary gaskets,Chris

Call me,305-394-3354,Chris

Your motor has 3 triggers in the trigger assy.They each fire 2 cylinders,1/4,3/6,and 5/2.Very likely you have a bad trigger,and this is how it would present,Chris

Don caught me🥹,.005 interference,not clearance…I need to proofread,Chris

Factory interferance is .002-.0025,and is sufficient as long as the motor dose'nt suffer an overheat,as that interferance is gone at 200-250 degrees.We install oversize sleeves at .005...

If the sleeve got loose enough to turn,pinning it in place will heep it from turning,but it won't keep carbon from infiltrating the gap between the sleeve and register.This will result in a thermal...

Definately change the reeds to composite,they often chip and break,sad to hurt a piston with a broken steel reed.We make good reeds and crankcase stuffers for your motor,Chris

Have you checked to see if a sleeve has turned ?,not uncommon on an O ring head motor,Chris

Lots of circumstances slowed us down,but were catching up...dont understand why I'm not getting calls,try my cell,305-394-3354,Chris

I don't believe factory oversize are available,but we have great aftermarklet ,Chris

Dry,No sealer needed,Chris

Well,Still very much in the biz...But due to several issues I don't have full control over we have been delayed way more than expected.Things are improving,and we are catching up,not as fast as I...

So,lets revisit the rotated sleeve,and decide why in fact it rotated.Two strongest possibilities...
1,Insufficient interference from the factory allowing rotation when the motor got a little hotter...

The sleeve turned for one of two reasons,either there was not adequate interference between the register(aluminum block holding the sleeve) and the sleeve,or an overheat occured that allowed the...

Our reeds are available as reed only sets or combo reed and stuffer sets for most motors.As to pricing,I can't control what a reseller does,but we do sell direct...See our website or call for...

Very common for the metal reeds in your motor to break,sometimes causing serious(rebuild time)damage...We have a composite that improves performance and is safe in case of breakage,call if you want...

way way lower

Your BB block is actually a 150 HP,if I remember correctly...Pretty sure.A 175 would be a CC block.The ports are smaller in the BB,Chris

We have reeds and stuffers,gaskets for your motor...the metal reeds chip and break often,it's a good idea to change to composite.Also,check your fuel pressure at idle,should be 36=39 lbs,if the...

I can help with the gaskets and install,give a call,Chris

Yes,I would advise to carefully lap the cages on 400 wet/dry paper and a little soapy water.Be especially careful to hold the cage flat,and don't allow any rocking.A lot of lapping is not...

Not at all normal,Give a call and I'll see if I can help,305-394-3354,Chris

Anyone farmiliar with the patent process that might offer advice,I have an idea I think might be patentable,but am not sure where to go next.Once before I had something that cost several thousand in...

Your motor is equipped with 5 petal carbon reeds,so you should be good for awhile...when the time comes,we have a much more affordable alternative,Chris

If you look around you can find good unhurt cranks for less than the cost of a repaired one,I don't use repaired cranks,Chris
