Here's a video, my son is in first and is running a Go .25 (Welch), second place (Bohlman) is running a Rb mod Sirio, can't remember the name but the new long stroke .21 for truggy.

http://www.mnnitroseries.com/gunner/...4%20Truggy.wmv

I rebuild alot of motors for local racers and a few on the board, anytime a guy with a v-spec says it won't run right its almost guaranteed the crank pin is worn and it needs a pinch. I do actually like the looks of the speed crank, it should last alot better.

Maximo,what the effect from the CRF crank,really!ORION is saying that it provide better fuel economy,how many minutes did it?

i am thinking to buy a motor like this,and i want to know if the crank can make a diference for these +100 plus bucks!

and something last,are really the jammin-picco[evo 2]-and now crf the same?even in shims?intake and all the others durations?

I have not timed a CRF.. but I really do not need to, the sleeve it uses has already been maxxed out by Picco so the only changes CRF could make would be to detune it ( which makes no sense)......... If you look at the dyno's of the old CRF.12 and then the PIcco JL you will see the CRF has nothing on the Picco, in fact the Picco is far superior... So I am not to sure that the CRF crank will offer any real advantages over the Picco crank......... For the $100.00 extra I would get a Jammin JPX modified....

most people will find it perfect, some will find it hits too hard, others may find it has not enough low end..I have heard reviews across the whole spektrum.... I only really run these mills as modifieds so i am not the best to ask how they run stock...... I can tell you the modified Picco .21's have by far the hardest hitting, nastiest, craziest powerband on the dirt.. from idle to 42K these motors are dynamite in your hand and will not be touched by any other .21's, modded or stock , only complaints I hear are they can be too violent for some drivers, and that clutches seem to fail more often.. motors that come onto pipe early like Picco's do tend to heat up the clutches more then a softer starting motor like a Sirio


I will say as a rule Picco's have awesome low end responsiveness, even stock they snap harder then any other motors I have run...so even with the short header the stock Picco's will still have a harder hitting low end then 99% of other .21's, only the OPS based mills may match the Picco for low end snap......

Neal, the video I posted above was from the Mn nitro series. There was a couple guys from Winnipeg there, actually I think Nick Moxley should be in the video.

I may have to change my tune a little on this... I have heard XRC has dynoed the new CRF 28, apparently the results are pretty impressive... The CRF crank may be more effective then I gave it credit for, I am going to look to purchase one of these motors to compare against the Picco version...... According to XRC the new 28 hit 90 oz/in of torque.... that is huge !!!

tho i have to say XRC's testing numbers have been extremely high lately.... ever since they dynoed the Sirio CL7B their numbers have been way too high.......... the latest one is they tested a TRX 3.3 at 1.4 HP LOL...the same motor dynoed only 1.06 1 year ago, and .96 2 years ago............. XRC;s numbers cannot be trusted anymore..... AB MOds or EB MOds for accurate dyno results......
