Maybe this is is silly question...............

Shortline, what made you buy so many of these parts and hang on to them? Did you buy someone out or get a great package deal?

I'm just amazed at the volume of parts that you have and I bet you haven't even scratched the surface with the pics you've shared!!

Regardless, NICE STUFF GUYS!!

This is a NOS 61mm Pauter Piston / Alum Cylinder Kit with a venolia race piston for a atc90 . Notice piston is already cut for their stroker crank set up .

Do you want to sell it?

That's the pump fuel piston. I used to run their methonal piston with the 61mm crank. I believe they were 14-1 compression.
Pauter changed the design of their balance holes in their 61's toward the end to a stepped hole instead of parallel because they used to form a crack from the balance hole to the crank pin which used to make the pin come loose.
I may have mentioned it before. I went to Pauter Machine in May 1982 and could have purchased their stroker jigs and numerous big valved heads etc but everyone including me was in love with the new 250R's and was thinking this stuff was old hat. DOH!

Very interesting thanks for the info .

I have one of pauters 61mm crazy alcohol venolia pistons / cylinder in one of my 90's but I rejeted it for 110VP race fuel . Its scary when cranking that puppy up and the crank case pressures are just ridiculous . LOL .

Here's my pauter...

Very nice . How does it run ? I like the BAPP stinger exhaust it looks in really nice shape .

I have that dam clutch cover, or something similar - I'm gonna email Shortline and see what it is

Clutch bracket on side, hole for kicker (had a kicker in it but broken off)

NICE KIT!!

[motoman1012002]

that is sweet

[90crazy]

I have'nt even threw a leg over this thing yet! Just bought it! The guy claims it runs great and it rips! That BAAP stinger is in great shape! What I thought was funny is the stock air box.

[Shorty]

Did you buy that from a guy in CA?

[shortline10]

Lots of nice parts on their . That bapp chain tensioner is the HD model and a rare piece . What does that intake manifold say on it ?

The manifold says HLM. The old owner said it was Honda of Lemon Grove.
