Montesa 4rt 260 2020 Bash Plate

[lineaway]

By the way, I use the slotted timing screw to fill the oil. It works better to replace it with the CSP cap. You can see it in my last pic. I changed my oil last night and remembered.

If only doing an oil change then buy a oil change syringe 

if doing filter take off bash plate and lay bike on its side.

change filter and fill oil before putting cover back on 👍👍

I'm a nurse so syringes are never in short supply. It's the only perk !! Very useful.

What oil change regimes do you use? Tell me in hours as I'm going to fit an hour meter.

My bike is brand new. Never been run in even. Despite being 2020.

I do oils ever 6 weeks approx depending what I have done or got coming up and change oil filter every other oil change.

on a brand new bike probably do oil and filter after 4 to 5 weeks then again similar time after then drop to every other.

I ride every weekend with an odd practice thrown in so in hrs probably 25 hrs but again depends on what sort of events done and coming up.

would do earlier if I had a national coming up etc

You’ll need a 500cc syringe - whatever they are used for 🤔🤔😩👍🤣

Do you change the gearbox oil at the same time you change the engine oil and filter.

Also what quantity engine oil do you put in if you have changed the oil filter and secondly if you haven't changed the filter and just the engine oil? 

Thanks gaz

yep always do both

Oil qty is in the manual   - manual is available on line .

Good quality engine oil  -ATF in Gearbox 👍 (and wait 🤣🤣)

Engine oil capacity after draining 0.41 liter (0.43 US qt, 0.36 Imp qt)

after oil filter change 0.44 liter (0.46 US qt, 0.39 Imp qt)

after disassembly 0.60 liter (0.63 US qt, 0.53 Imp qt)

Ive read a lot of posts about ATF in the 4rt. Why not ? My old beta rev loved it and it made the clutch so much better. Oddly in my Evo I've always ran putolene nanotech in my Evo 2t to good effect. 

I was asking about the oil quantities as the betas run considerably better on less oil than is manafacture recommended. I was wondering if the same applied to monts. You obviously go by the book and I'll do the same.

Go by the book but be careful not over fill the engine as some have reported on can push crank seal out on gearbox side 👍👍

always check on dip stick after 👍

One of the benefits with the Montesa is that the engine and the transmission oil is separate so if you want to play a little with amount for how the clutch response, as I know some have, I suspect it shouldn't cause to much of an issue to set it a little lower (not to much as noted though). 

On that note I have done a little testing with different oils in my 07 4RT and my 17 300RR and in the process did end up with a little low on the transmission once but didn't find it made much of a difference.  I found that the type of oil made a much bigger difference in how the clutch felt than the amount did.  I have had the best results with the ELF HTX740 and the NILS Clutch Trial and I suspect I could get even better results if I switched out the plates to the after market dimpled set. 

Hope that helps a little on the perspective side of the fence.  good luck.

Thanks for the info. I'm days away from my first outing on it. The Mitani bashplate should be here by the weekend and all the protective covers are in situ. Once it's fitted I'm good to go !! I'm almost looking forward to my first oil change .
