MVT inner rotor

Simon Helgesen /

Hello

I’ve just installed MVT inner rotor ignition.

In the usermanual it says to drive without the flywheel cover, to get enough cooling.

I’m going to ride a lot of gravel roads, and I’m worried that rocks and water will fuck it up.

What would you guys do? Drive with or without?

Puch maxi, max rpm 8-9000

Yea that’s the problem with pull start hpis too

It’s clearly says don’t cover

Re: MVT inner rotor

If it says not to, I wouldn’t.

The parts should be water resistant? I would guess people building ignitions would do that for us. If not there are products like this:

As far as rocks go, maybe cut the face off an old flywheel cover and louvre the sides. Plenty of airflow, but keep big stuff out.

I trust the big external flywheel to do all that on my CDI Setup. Never really thought about the problems with an inner rotor before. Those are my initial ideas. Does it sound like a reasonable approach?

Or regular old WD40 . ;)

Re: MVT inner rotor

I never thought about using WD40 for long term waterproofing. Wouldn’t it get messy from reapplying and collecting dust?

I use: T9 Boeshield on all my motorcycle parts that I don’t want to rust. I just googled it and seems like it’s acceptable for ignitions. It’s waxy, so still collects dirt and stuff. But, it’s a one time application.

On this side of the pond, WD40 is an expensive exotic import. If someone is gonna shell out the cash, might as well last a while.

Here’s the description on American amazon. I think it does collect dirt, but they say it doesn’t. Anyways, it is a very good product. One can lasts a very long time. Two thumbs up for keeping exposed metal from rusting in Ohio winter road conditions for years.

“ On a seafaring yacht, a dusty ATV, or a shower door, T-9 has you covered. Boeshield T-9 endures muddy bike trails, rain-soaked back roads, and salted highways. It withstands farmer’s fields, offshore oil rigs, and carpenter's workshops. For everyone from firefighters and road crews to cyclists and sailors, Boeshield T-9 is the proven solution. T-9 attacks existing corrosion, loosens rusty parts, and flushes out old lubricants. It is also extremely useful for drying wet parts, electrical motors and circuits, ignitions, and connectors. Apply T-9 and wipe off the excess for immediate use. T-9 dries to a waxy, waterproof finish without leaving a sticky film to attract dirt, dust, or mud. T-9 stays liquid long enough to permeate metal crevices and seep deep inside assembled components to leave a durable protective coating as well as lubricating and protecting-all without dismantling your equipment. Apply T-9 to any metal surface and let it dry. One simple step gives you a thin, penetrating film of durable, waterproof protection and lubrication that endures, months after month or mile after mile. T-9 dries to a clean, waxy, waterproof film that won't wash off in rain, puddles, or mud. You can rinse away sand, dust and grime with water, while leaving the lubricant intact. T-9 will not harm paint, plastic, rubber, fiberglass, or vinyl. It can be used on engines, wiring, and belts. T-9 is nonconductive and will not cause short circuits, so it's also safe to use on electronics. Use solvent or any emulsifying cleaner to easily remove T-9, or simply respray and allow T-9 to dissolve itself before wiping it off.”

Boeshield is very good 'stuff' , for what it is .

WD40 doesn't collect much debris and if some does appear , just give it another quick spritz and all is well in the world , again . ;)
