TBR7 Performance Head Pt. 2 The Results

[@stevelyons6739]

Looks much better without the decals.

[@audiomonster303]

After proper break in I am def gonna port match and polish in that head!

[@Maxumized]

Vibration can be caused by the flexible metal loop keeper for the wire harness under gas tank. Mine would expand and rub on the tank at certain rpms.

[@xmoto7377]

Noname the vibration wasent just one thing, you can feel it throughout the whole bike, with the extra power it vibrates just a bit more. Not much but enough to notice but I know exactly what you are talking about it runs really close to the tank

[@bigoc55]

Great video I’m in northeast philly. Just picked one of these up. So your videos have been very useful. We should ride sometime.

[@whalesong999]

Just off the cuff, the bigger the carb bore is, the more it wants an accelerator pump to offset the low rpm bog. Haven't followed your channel but the topic is interesting. I ride my daughter's RPS Hawk and getting familiar with it - I'm a retired mech from back in the '60s and '70s. I notice her bike seems to vibrate more than older 250s I've ridden; have discovered it has a harmonic chain whip with power pulses that changed considerably when I went to a 17/45 sprocket combo.

[@xmoto7377]

You know I am thinking about experimenting with getting a PWK with an accelerator pump because I have noticed the low RPM bog. That would make a whole lot of sense!!! Thanks for the info!

The Pe30's manifold is the reason you're having to run that large of a main jet.

​@@xmoto7377 what did all those engine upgrades cost? ...without paying for the skilled mechanic labor?

[@jude2485]

What do you mean port match the carb to the intake? Did you mean the intake to the head? Please explain. PLEASE!!!🙏🏼

[@xmoto7377]

When you cut the intake to fit the carb on the bike the geometry of the intake to the carb is no longer in line, meaning there is a hard edge air flows right into. Go watch the install video I made I show you how I cut it if you did not cut the intake. The intake has to be grinded away with a dremmel on the inside so the airflow does not hit a wall and disrupt airflow. I supposed you don't absolutely have to, but if you want maximum performance and easy tuning you should def make sure there are no hard edges or restrictions in the way of the air flow. Open the slide with the carb on the intake and look inside with a flashlight to see how much needs to be grinded away

[@xmoto7377]

@@lv-blackhawk my top speed with no head wind on a flat stretch of road is 75 mph, and yes I have verified with the GPS. I am only able to reach this speed because of the extra power the bike has now from all of the performance stuff I did. but what is your RPM at 62 mph? and if I were you I would order either a 42 tooth or a 40 tooth rear sprocket.

[@lv-blackhawk]

@@xmoto7377 Yeah you definitely make sense! I need to order a 40 tooth sprocket and see what that would do.. Right now I have the 17 and the 45 on the rear, I noticed once you get to 5th gear there's not too much top speed left. If I would do it all over again I would never purchase that bike by the time I have spend the money to upgrade this piece of s*** to make a reliable bike I already spent about $2,500 it's just not worth it but it's too late now I already jump in the river I got to get myself out of it...

Raising the needle richens the middle/part throttle. Lowering the needle lean's it. You probably do not have a main jet issue.

Fork guards are "universal fit" guards from amazon, but you have to modify them to fit, they are not simply "bolt on" drill a hole in em or two and a couple zip ties later and they are on! It is 100% for looks tho since the forks are not upside down forks!

What oil did you use on your first oil change?

First oil change I did conventional moto tech 10w-40 then switched to AMS Oil 10w-40 full synthetic at 400 miles.

[@OddBallPerformance]

Oh, as far as your top speed, you are having the same limitation as every CG250, even with a ported head there is just not enough cam to push past about 8000rpm in 5th with higher gearing. With your gearing that should be over 70mph, 73-75mph tops. I would say you might be rich enough that it is causing you a little top end power

[@xmoto7377]

thats what i was thinking, thats also why i made the dyno appt. i just got in today a 172,170, and 165 jets and might try them out, but final jetting will be achieved on the 16th with the dyno and i will still have it slightly rich just for it to run cooler and for when the temps drop i dont need to rejet.

[@xmoto7377]

i am going to keep the 175 in there for the first dyno run just to see how rich it is then slowly start stepping down in jet sizes.

[@danielbruno2631]

buddy i need your help, how did you use the nibbi with the stock airbox? lease let me know asap! TY!!!

[@xmoto7377]

Alright so you have to pull out the stock boot and buy a silicone tubing with a 45 degree angle that has an opening on one end close to the size of the carb and use a clamp to keep it on, your going to want to open up your air box take out the paper filter and start cutting out the webbing to open the air box up with a dremmel. Then use the dremmel again where the stock boot goes into and open up that hole until the silicone tubing fits into the hole, then just make sure you buy a pod filter that fits over the silicone tubing and there ya go, you can decide to run with the air box lid on or off, just be sure to adjust jetting and dial it in

Oh also use black permatex silicone to seal the boot to the air box, on the inside and outside to keep dirt and water out

The bog is too rich..with porting a head it flows more air over the main jet so you need to lean the main jet for sure...

[@xmoto7377]

Check out my dyno video after this one, air fuel ratio was pretty much spot on. Air fuel chart shows a lean spike when the throttle is opened rapidly and when it bogs. To eliminate this a smaller carb would generate more draw minimizing the problem, however it also minimizes horsepower. Also draw is reduced when flow is increased, gonna try a PWK carb for a stronger draw next season and try to eliminate the bog, and will be strapping down on the dyno again to verify jetting

[@patriotrob7066]

If it starts that easy with no choke I'd say that jet is to big
