Factory 225 cylinder kit, stage 4 (barrel, head, piston kit) MRB


Now that we have our new race-tour pistons available we have remixed the popular factory tuned stage 4 200cc kit to include the new piston.

This version of the kit includes the cylinder bored out to 70mm, an Indian head reprofiled to suit, all the studs, gaskets, nuts and washers and the racetour piston.

This kit still has 2 oversizes available.

We recommend our Dellorto 25, 28 or 30mm carburettor kits with either a Clubman or our MRB Dev-Tour stainless exhaust systems.

This kits produce between 16 - 23HP.		 Factory 225 cylinder kit, stage 4 (barrel, head, piston kit) MRB

Melv on 02 Jul 2009 asked "The factory 225 kit stage 4 will it run a stirling pipe n wot top speed wil it produce with no tuning I'm looking 2 buy 1 very soon "

MB Group, Serious Outdoors Ltd replied: Sorry this is a pipe that we have not tested so we would be guessing.

 
 

Rob on 15 Jun 2009 asked "I have a question about "Factory 225 cylinder kit, stage 4 (barrel, head, piston kit) MRB" have you done anything to the barrel if not how much would a properly tuned stage 4 or 5 barrel cost ."

MB Group, Serious Outdoors Ltd replied: We bore out the cylinder, chamfer port edges and generally clean them up but don't go over board as the Indian castings are very poor and requires a lot of time to perfect. As they are they work well, we do offer a fully tuned extra which costs around £200.

 
 

Eric W on 22 Jun 2008 asked "Does this kit bolt straight on after fitting a new crank"

MB Group, Serious Outdoors Ltd replied: Yes the cylinder kit bolts straight onto a standard crankshaft with a standard 107mm con rod and again if you use our better Race-Tour crankshaft with the 110mm con rod, you just use the packing plate that comes with the crankshaft.

 
 

Heiko D on 22 Jun 2008 asked "I want good Kit for touring and City use. If I use this Race-Tour 225 Kit with the Devtour Exhaut and 30mm Carb do I get more pulling power and lower Revs than a TS1 or RB Kit?"

MB Group, Serious Outdoors Ltd replied: Yes this kit gives bags more low down pulling power and will do as you request.



They usually give between 16 -19hp.
