    Hi all I just got the bmp kit and my robin engine today :grin5: Im a newb to engine and all that.

    Now I'm gonna try to install and I would like some help and advice on breaking in the engine and if I get stuck somewhere.

    On the breakingin I have read that I should go back and forth fast and slow for 15 min, let cool, and repeat 2 more times but for 30 minutes and then it should be ready to ride?

    I have search the forum on oil and gas. I read I should use synthetic blend, so what is a HIGH quality oil for this? I will also use the highest grade gas for it is that ok?

    Thank you!

    Modern engines do not require running in. Thrash it from the start, it wont make any difference.
    Change the oil after an hour for the first run.

    I would avoid wide-open throttle conditions for the first couple of hours, and vary the speed during this period as well (don run for long periods at the same engine RPM. ) You might get away with no damage under Garp's recommendation, but, it won't hurt (and could help a lot) to not "thrash it from the start."

    Use regular oil for the first fill, then switch to synthetic at the first change. (using synthetic oil from the start can lead to a longer 'break-in' period before the engine develops full power. ) Suburu recommends the first oil change after 20 hours, then, every 50 hours.

    Anybody have any idea how to hide the engine? Anything I can use to cover it but not overheat it? I read about the idea using a basket but I don't have tools for that and too much hassle.

    I agree with above .

    I have seen people take a milk crate & try to hide the motor. Since you are wanting to hide it,, I presume you are riding it illegally ? Good luck & be careful !

    Isn't it a JOY to be using quality made products on your new mb? Didn't you just love the ease of installation? How about BMP's and Robin's instruction manuals. Nice, huh? Sometime around 100+ miles you'll notice an increase in compression. The valves and rings will be seated. She'll pull a little more when starting and have more top end and acceleration. Why hurry it? Take your time and you'll have a fine mb drive setup for years to come! You did install belted tires and Thorn resistant tubes didn't you? If you did or will you can leave the HT 'toolkit' at home!

    I don't want to start a firestorm here but like Loquin suggested, breakin w/ good quality petroleum based oil. Robin manual suggests viscosity and ambient temperature combos. Then consider running synthetic. I've been using Supertech Synthetic 10w30 oil in my Titan 50. Seems to be doing fine. From WalMart, claims 100% synthetic formula, cost here is $3.98 per qt.. If you prefer Castrol, Valvoline, Mobil 1, etc. Synthetics, Walmart was a little cheaper than auto parts stores.

    Oh yeah I'm enjoying my ride now! Went for a 60 miles ish ride today :D Now when I look at a map, it is a totally different thing haha

    I did run into a problem the engine started blowing out smoke for a couple min and leak oil everywhere but that was because it was tilted at 35 degree angle (and when I pour in oil i pour in tooo much since it was tilted) so had to drill 2 hole in that metal thing to raise it up. Now it alll good

    As for the oil I use the 10w-30 Castrol syn blend even for breaking in. Im buying the best stuff for this engine hopefully last me many years :D

    So glad to hear you're enjoying your Robin. I just installed a new Honda 35 on a BMP for testing. Angle is less important on the Honda because of the 'misting' oiling system. But, the clutch is noisier than on the R/S and the Honda's got a belt driven OHC valve arrangement. Don't know how it'll hold up. I've spoke to James at BMP and he favors the R/S over the Honda. They just run like a Swiss watch!

    I recently bough a BMP friction drive kit and installed it with a Tanaka PF-4000 2 cycle engine.
    Let me tell you, I love it!
    It runs great. All the little kids' eyes bug out, their jaws drop and they all point at me when I ride by!
    I think the engine is a little noisy though, and will switch over to a Robin/Subaru EH035 4 cycle engine very soon.

    rohmell,
    I got the Subaru Robin E035 but think I may want to try out the Tanaka or a GP460. Let me know if you want to sell your Tanaka?

    I installed a muffler that is designed for the TC-4700 and it quieted the engine to a very acceptable level.

    I think the BMP kit (if they are still available) and the Robin-Suburu engine are the best way to motorize any bike they will fit on. I love friction drive, it's only issue is wet roads. I have an old '70s model Solex that I have ridden thousands of miles. Properly adjusted,, excess tire wear is practically non existent, and they is very little to break.

    I would like to experiment with some other drive systems, perhaps even an HT engine, but for dependability and daily use, I just don't see how you can beat the BMP/Robin-Subaru setup. Jerry.
