Botanas 70cc MB5 Kit

anyone running this?

https://www.doscycles.com/products/honda-mb5-botanas-racing-45mm-70cc-cylinder-kit?variant=8123855175782

guessing it's similar to the treats import kit?

Any tips, tricks, reviews?

Going to be running it with a vm20 and starting off with a 150 jet and working my way down. Is that a good starting point?

Womp womp

Re: Botanas 70cc MB5 Kit

I have that, its solid. I mostly got it cuz it gives a lil boost to torque. Like it's almost no faster top speed but you don't have to ride the clutch and keep the revs so high.

As for tips, the hpi woke it the fuck up. I got an ns carb and couldn't begin to guess the jet, I wanna say its bigger than 150 but 150 is probably a good start, mikuni is less steep a jump between jet sizes once they get bigger #s (numbered by flow vs diameter scales linear vs squared)

Re: Botanas 70cc MB5 Kit

awesome thanks for the reply. i was hoping it would give me a torque boost. I'm ok with my current top speed of ~50.

I started installing it yesterday, think i might need an intake riser for the MB5 carb, or might just bite the bullet and by an MLM intake.

Re: Botanas 70cc MB5 Kit

I'm not okay with 50, I want at the very least a usable 55. I'm using a stock cylinder with a home made pipe and a 19mm OKO. I recently went up to a 15 tooth front sprocket and hit 54 but it didn't want to wind out to get there. Struggling to pull it in 5th really. This kit could be the answer to more top end after re-gearing?

I'm gonna give it a shot... Stay tuned.

My kitted MB5 does 55, but I run a 12 or 13 up front? I cant remember which off the top of my head, but it gives me mad torque, could go much faster though if thats what your going for

I mean you already have the kit so why not put it on?

Re: Botanas 70cc MB5 Kit

Wait... holy shit... I FORGOT!!

LMFAO!!!!! I figured you did......

Re: Botanas 70cc MB5 Kit

Found it... I will report back. I did 57 tonight on the stocker. It needs road to do it, but it got there.

Re: Botanas 70cc MB5 Kit

Looks like it could use some dremel work.

I had a MB5 that I built back in 2007 that had this 70cc polini kit , HPI, boysen reeds, 21phbg, homoet pipe and a 14 or 15 in front that would cruise at 65 in 5th. I sold it to Ryan Nash in 2010, not sure where it ended up.

Re: Botanas 70cc MB5 Kit

so getting the piston in was a mother fucker. not sure if the rings were too big or what.

sanded the ends and i eventually got it on. paired with 70cc head and a vm20 it runs like shit.

running a 150 jet, i think that my plug might actually be super fouled so i'll replace and update.

Did you size the ring gap before installation ?

I did the same with a 6-speed trans, it was soooo fast, but with a Homeot it was pretty miserable to ride (imo), you had to keep it at 9500 RPM or it didnt make power, just a lot of shifting, but fast as all get out

Nahhh dude your lean as hell, if your running the stock CDI and a pipe start at like 180

Re: Botanas 70cc MB5 Kit

so one year later i'm playing with this again. I deleted the oil pump and installed the blockoff plate that i had kicking around. Also fixed the leaky gas tank (hopefully 3rd times the charm). Only runs with choke on and revs to the moon....air leak?

Re: Botanas 70cc MB5 Kit

Well I'm dumb. Turns out the reason it was revving to the moon is that the throttle cable was hung up and had the carb 3/4 open. Also, the reason it would die immediately on throttle is because of the stupidly small jet. I initially had a 150, then went down to 135 after some posts I read. I guess they were talking about 50cc because it runs perfectly after a 180 jet. (vm20)

Re: Botanas 70cc MB5 Kit

I've never put a completely off-the-shelf VM20 on a bike and not had it run immediately with the 180. The fine tuning will go up and down, but literally 5/5 bikes I've run them on just start and ride with the 180 in them.

Re: Botanas 70cc MB5 Kit

Yeah, i guess they sell it with a 180 for a reason. I have the entire range of jets and a tons of needles so def some fine tuning after some plug chops/temp monitoring. For now though she's roadworthy....or at least enough to get me to the liquor store and back.

Iā€™m dying šŸ¤£

Re: Botanas 70cc MB5 Kit

Yeah I'm running a vm20 on my mb5 with a stock cylinder, MLM pipe, screen air filter, and I'm running a 165 main jet. Kinda feel like I could go 170 ...
