Help us Help YOU.  Every year we get back a low percentage of cores we send out and it is becoming a real problem for our customers.

MCB is in need of most all GOOD cores for the Ski-Doo engines and happy to pay for them.

Monoblocks 623240 / 242 /246 / 249 / 041 / 046 etc. (see last three digits)

Singles 623262, 852', 436, 483, 480 etc.

Look under your benches, in the sheds, and on the shelves folks.... and CALL US . We'll make it easy and email you a ship label !

thanks folks - MCB Performance

Machine is not here to diagnose in person.

2014 Etec 800 Engine is new and recently replaced and runs very strong. Did not have the issue prior to engine replacement. 

Starts and runs flawless but randomly ABOVE 6500 rpm it will "shut off" for 1-3 seconds and then immediately "turn back on" and continue.

Any thoughts folks? Sound like a voltage drop perhaps shutting down the injectors? Fuel pressure drop out? Ground issue? 

thanks - MCB Performance 

MCB is in dire need of a good set of 500ss (600 non-HO) crankcases. These need to be the LATE (XP chassis) version with the cast in boss for side mounting. 

Computer shows we had 2 sets but looks like they were labeled incorrectly and actually the early ones.   

Thanks folks. - MCB
