[Battery upgrade]

Now if you were to use a few of these batteries in parallel

https://hobbyking.com/en_us/zippy-compact-4000mah-10s-25c-lipo-pack-xt90.html

Specs:
Capacity: 4000mAh
Voltage: 10S1P / 10 Cell / 37v
Discharge: 25C Constant / 50C Burst

 

This would give  your 36 ish volts, at whatever ampacity(wattage) you need.

You would still need an appropriate balancing charger.

 

 

[Battery upgrade]

I use the Turnigy 3s -2200 mah batteries in my RC Helicopters.

They are very good batteries...but for charging you need a proper lipo charger with built in balancer or you can use an external "blinky" (balancer).

Either way you can only charge 1 pack at a time, per charger.

While you could try and trick it into charging the combined packs together, over time you would see a serious degradation as the cells would become too far out of balance in each pack.

Well. there you are Mr ahh_me2. I bet you never thought your first post on the forum would provoke a discussion on the physical properties and chemical composition of WD40.

I guess you're right!  lol

Oh well, there's always something new to learn...

The white thing is a sandblast cabinet, and the grayish bomb looking thing to the left and back is just a 100# propane tank.

 

Uh yeah, I'd forgotten about the application of oil to the chain with a paintbrush....Thanks for the reminder!

 Now you are on a trials bike......just slacken  the chain off until the top of the rubber tensioner chain slipper block has a gap between it and the underside of the rear swing arm that you can fit your first/index finger tip in and that's it.......the chain is too tight in the picture.

Yeah, I was dealing with fluids today so didn't get much chance to look at the chain.

I know I'll have some questions about it though...

I do know it needs some lube, not sure yet what should be used.

You chopped all those trees to find a suitable bike stand!

It seems I have bike stands scattered all over the yard! Very convenient I must say.

[Checking coolant level]

So not knowing what coolant fluid was used, I ended up draining the whole thing, I didn't get very much out, it must have been pretty low.

It was a blue liquid, I'm thinking it's the Arctic Ice coolant that is sold around here at the moto dealers.

I guess once it's a known fluid, a person can simply top it up on a regular basis as there doesn't seem to be any way of determining actual level.

All part of the ongoing maintenance of a trial bike I suppose.

Thanks for the help!

[Checking coolant level]

Thanks, was able to push the box over enough to unscrew the cap and remove it.

Using a mirror I looked down the spout, it goes down 2 inches or so then branches off at 90 degrees, couldn't see any coolant.

Should coolant come right up to the top?

The handling was just fine when the last owner tried it. https://youtu.be/gTVoFCP1BLg?t=1m6s

Fair enough!

I knew something was off, couldn't put my finger on it though.

So I phoned home....long distance of course...

Followed the recommendation, thinking it looks better now.

[Checking coolant level]

ummm, new guy and newbie(trials) here.

Just bought a 2001 Rev3 250 and wanted to check the fluids, after removing the plastic cover on the left side of the frame/tank, I saw the "rad cap" but it seems there is

a plastic/metal block preventing it from un-threading upward, what am I missing? other than a few brain cells lol

Here's my view of it:

[Older newbie, first trials bike]

Hey all,

Greying beard, rode lots of dirt bikes and some motocross over the years, not a pro by any means, just riding for fun.

Always wanted to ride trials...

Been reading this forum for a while trying to gain some knowledge about purchasing a used trials bike.

Being in Canada, trials bikes are few and far between, and I didn't want to spend too much to get into trials at this point.

I finally found an older Beta Rev3 250, 2001 for a low enough price, it was probably more used for trail riding before though

but seems in reasonable condition otherwise.

While I have numerous questions...lol... I will reserve those for future posts and use this as an introduction only.

And YES!!!   I will post the mandatory trial porn pics of my latest acquisition!

Oh , and did I mention I'm on 3 acres of land and I've been doing a lot of logging lately....hmmmm, what to do with the logs....tough one! cut em' up and burn em?

Thanks for having me here, I have lots to learn so will go back to reading with my mouth shut!
