Husky race motor

Thinking of having a HOT Husky 250 motor built. What would be some of the features I should be asking for to improve performance but maintain some level of long term reliability and where in the USA could build this motor...Race Gas only motor, hi compression, Case matching, crank balancing, porting etc are a few I know of ....Any thoughts are much appreciated.

Call George Erl at Up-Tite in Santa Ana, CA. 714-540-2920. He has built Baja winning Huskys for many, many years. His motors flat out haul the mail yet stay together after hours of high speed running.

Thank you....I plan on ringing up George..

Is this for the MAG? It is nearly a true replica of a 1973 prototype that placed very well in the 1973 250 GP season. It never needed the power you are seeking.

Not for my Mag....that's runs like a beast already. Plenty of power on tap there. It's for my 76 Woods racer husky....needs a little more snort. It's old and a bit tired and needing a refresh so O thought I would go all out if possible...

I would recommend the case matching, crank balancing, full circle crank, and porting that would enhance the mid range. I saw a writeup several years ago about mods that were made to an 82 250XC. The result he got from giving the exhaust port the same duration and timing as the 430 gave him a 250 that"pulled like a big dog.A big angry dog" Awesome midrange. Changing to a Lectron carb would give better dial in capability. You really do not want to reduce reliability. Getting it fresh and cleaned up without the porting should give balance and desired reliability. Anything that exceeds optimal stock performance comes with diminishing returns. Just some random thoughts.

All great advice and thoughts Jimspac...I agree that reliability is a major concern and once you start monkeying with too many mods reliability quickly fall off..I'm going to require case matching, true and balance crank, freshen everything else up and ceramic bearing thought out. Should be good and strong. I ride at an expert level and can always use a little more HP in the right place in the power curve. I was able to dial the suspension in last year and now it's on yo the motor to end up with a vintage racer that handles great and runs strong ....only high performance interests me....K look at like firearms, a gun that shots like crap is of little interest, only accurate firearms interest me...

In the interest of better turning ability you may want to update to a 77 CR or 78 CR or WR frame like I set up for Ruwfo's 76 360CR. I am personally partial to the 78 WRs as they turned much better than their successors. I have 2 78 ML frames left but those are reserved for personal builds. I am building a 78 390WR ISDT Replica with the frame with the Timken cups and with the 78 Auto frame I am creating a conversion Timken retrofit for ball and cone frames like your 76 frame. After the kit is developed the frame will be the basis of the TT500 powered multisport I have in mind. I have a 78 OR frame I removed the steering neck from and put the bearing cups on the frame I sold to Ruwfo. I will be welding in a steering stem from a 1985 KX125 I parted out a few years ago. I plan on establishing a rake angle of 28 degrees. I am going after Maico handling by dialing rake, trail, and swingarm angle.
