alright guys, i just picked up the motor over at esr. it is an 86 bottom end with a long rod now on a 3mm stroker crank. it is also in an 86 frame. Ok, i dropped the motor in with no problem, but went to put on the carb and intake tube i noticed that the cylinder had moved up so high that the throat of the carb points right at the rear shock mount almost and there is no room for the esr filter box eliminator tube nor the stock air box tube. How do i go about solving this problem? i have not talked to esr as it was already too late by the time i discovered the problem. But i am sure that someone on this site has encountered this problem becasuse i dont believe that this a very wild not uncommmon motor combonation. please i need help fast, going to glamis in 2 weeks :unsure:

What are you using for reeds/intake boot? Are you using a spacer?

I have never had a problem with this and I run V-Force reeds w/a 3/8" reed spacer and a UPP big bore intake boot and an ESR airbox eliminator.

The only thing I can come up with is maybe the intake boot? Is yours stock? If so maybe try a UPP or CR style.

I think he meant that the problem is the height of the intake and the height of the crossmember for the shock mount. I don't know if the crossmember is different on the 86 from the later years. My 88 with long rod engine is a tight fit between the OEM air box boot and the crossmember but it does fit.

Gotcha. It still may be possible that the angle of whatever intake boot he is running may play a hand in this!?

That is true. I use the cr intake boot, no reed spacers, and a 38 TMX with the ESR air box adapter ring. Fits perfectly with long rod engine and 88 frame.

yes i am using the stock boot and it is the angle of the boot that is the problem. it was perfect before but now with that spacer plate it wont fit. if the boot would be angled down a litlle more it would clear just right. i will call esr today and see what they have to say and i maybe buying a cr boot today just to try.might have to come up with something my self. Iam also using v force reeds with no spacer.

Yep either a CR or UPP intake should take care of your problem. Good luck! :rolleyes:

not all CR boots are the same. i believe they all allow for a bigger carb but i believe that its the '89 that is the less restrictive and works best
