That's a special box-o-saw. Haven't seen many 346 g's.
BR 400 nice?

^The face you make when running a BR 400 after using this bad mamma jamma.
Yes, however this particular mtronic saw has some goodies on it that make it a little heavier than the real apples to apples difference is. West coast clutch cover, roller chain catch, dual large dogs, HO oiler and stiffer AV springs to name a few. Someone swapped the full wrap for a half wrap or else it would be a complete “R” package saw.Mason, does the non M Tron seem a bit lighter than the M Tron version???

Cool, I like my big bore Honda’s! What year cr? 83?It's going to be a great long winter with some good shop time.
Been hoarding Honda CR250R motor parts off of Ebay for the last month or so. Going to make a nice bikesaw to go along with my little YZ125 saw.
The Honda is not going to be a ESR 330 big bore bikesaw but it will handle a 18"-20" pine log just fine with just 50h.p. Don't need 60 horse.
Both engines are going through a total build with carbon fiber and titanium (fricking expensive).
The right hand ignition Honda will have the same profile as the little YZ125 in the back ground.
Both will have bi directional PVL ignitions to reverse their crank rotations.
They'll both be light and compact for the cold start contests. The YZ will be the weight of a 3120XP.
CR250 running 28"b/c, YZ- 18".
Still got alot more stuff coming in the mail, parts out of the UK are taking forever.
Got brand new Mikuni Super BN jet ski carbs coming, their going to work really well, especially in the down draft position what they're designed for. Perfect for my 2 saws.

Are you going to modify a trx pipe? Vforce 3’s, you going to run trx or cr style reed cages?It's going to be a great long winter with some good shop time.

Hey Mac , I was looking for your TrX thread.Are you going to modify a trx pipe? Vforce 3’s, you going to run trx or cr style reed cages?
Yes from what I can see the TRX pipe with a bit more curve in the header pipe will fit my CR250 and YZ perfect.Are you going to modify a trx pipe? Vforce 3’s, you going to run trx or cr style reed cages?
Led build some nice pipes indeed! With porting head work and pipe you could get into the low to mid 40hp range with the 250cc pretty easy, the 330 should hit 50hp reliably and be easy to start, less compression, and have a wide power cure. the oem cage isn’t bad, the 01 cr cage with 07 reeds is supposed to support 50+ hp. A stock 01 is 47-48hp. Looking forward to the build!Hey Mac , I was looking for your TrX thread.
Yep it's a 1983. The birth year of the CR250R up to 2001. No power valve, porting looks the same as the CR's in the 1990s.
I picked that year because it's the last year they had right hand ignitions which my YZ125 has and I want to build them both the same profile which works for me. PVL ignition makes them run reverse rotation so I can get the b/c on right hand drive.
Arlen and Chris at LED make beautiful pipes and that's who'll make mine for both saws.
I'm running Boyesen Pro Series carbon reeds on both factory reed cages with stoppers deleted. Would like to try a ESR v force 3 series on the CR250 but I think the Pro series with a ported factory cage is all I need.
Crank works will true and weld the pin on the crank along with a new ProX rod and bearings.
In the last month I've learned a ton about the cr250r, very impressive engine.
