421 Serval used one season top end kit f/s.


Recommended Posts

I purchased this new Serval cylinder last year and its first run was over the last Halloween dune kick off at Glamis. I think I made five or six trips out the season, so it has very little use.

Porting flash cleaned up by a buddy of mine that builds race engines for motorcycles who also has a lot of 2 stroke experience as well. The domes and pistons have ZERO carbon buildup... No, I didn't clean them up! Ran with Yamalube 2r.

Pump gas domes from Redline, Wiseco 68mm pistons/rings are for a long rod 4mil crank. Stud extenders, new head studs, plugs are Yama bonded in place.
Parts & nikasil look great, no surprises... A couple of small scratches that any new cylinder would have after a short period of runtime.
Cylinders are painted with actual Yamaha paint so they look stock ish from a distance. Lol

I'm looking for $900 obo  head not included.  newer head studs
You cover paypal fees, I'll cover shipping.

Damn... I was gonna pull the trigger on that purchase right now!!

Is that a Mattoon head?

 

So, cylinders, pistons and domes for $950 and it's not ported by any stretch?

 

What are your plans?

What are you going to do now?
421 Cub?

That's a Chariot head.

Going back to a stock cyl 4 mil ported by Redline.
Tired of burning my legs on my CPI's so they're gonna go too!  Back to Fatty's!!

 


BTW:  The price was supposed to be $900, OBO but I can't get back in to change it....

May I ask why you're going back to a stk cyl 4 mil?

I'm getting ready to pull the trigger on a Redline build.

I'm torn between the Serval or a 4mil stk cyl.

 

If Serval, I'll run Snipers.

 

I burnt the shit out of my legs on my T5's last trip to Pismo.

I was riding in my convertible riding shorts/pants.

First 5 mins of carving the dunes, two 2nd degree burns on my right leg.
