That would be a deep breathing 720!!! Scary....like the wolf that blew down the house of the 3 little Sand Pigs!

 

I think that the only engine builder is Trinity and Sparks. We know that sparks is a one man band. Trinity has 15 or more employees. 22,000 plus forum members and NO One has a motor by any of the other companies????? Those companies might as well pull there adds. I can't belive that a company would not do head work, since the raptor runs out of steam so early.

 

Well maybe split the work between them. The head going to Trinity for valves and porting. Killer combo!

The other company does work on Raptor motor is LRD
As you know LRD have a good engine program on 250r, Banshee and 400EX.

I have look into and talk to them over the phone, They do the head work too. It almost what spark and Trinity do to the Raptor.

I think it would call 680 kit from LRD.

Theres two more places besides Trinity and Sparks that can build Raptor motors in my opinion (this is based on places that are known and that I've dealt with) and they are Micky Dunlap's shop and Robertson's Cycle.
You should be careful not to sell old mickey so short, he's been building 4-stroke motors longer than most of us have been riding.

 

I agree with you on the Mickey thing. There are a few people on here who don't care for the way he works, but I still think he would build a good motor. Another place that does Raptor motors is Bikeworx, although I have heard they are over priced.

 

Just......

Knowalsot and raptorrc made me think about this.....


If you have a big bore raptor, speak up on who built it?

 

SPARKS 690 KIT WITH 12.5:1 COMPRESSION, FCR'S, AND X-6 FULL EXHAUST....
HERBDON OUT..

 

I dunno just kinda felt this one should be back in the Mix.

 

It's back!
