What washer ya got?

Just a Karcher K3 but I bought a decent snowfoam attachment from detailing shed a few years ago. The attachment was about 70quid if I remember right.

I have a really good wax on the bike which helps with cleaning.

Yeah I have a snowfoam attachment from detailing shed as well as snowfoam ( bil something or other)

I've a nilfisk 140.
Only gets used rarely though, on the car about 3 times a year and cleaning a bit of moss around the house.

Bit hamber, good stuff that. You mean you dont clean your bikes after every ride?

Bummer Nialler, get yerself onto ebay, might find a clean 2nd hand part.

Set my air gap in project Drastics forks, 7 inches baby!

Reminds me of me 3 weeks ago

Metz what Zub? Are they a performance or all rounder tyre?




Replaced the spurious gaskets I used when blasting the engine with oem. Swapped the original old oem crank end oil feed seal with a viton skf. Worn crap seal here can reduced oil pressure to the head and kill the top end:eek:

I saw a grenaded DR650RS with the valve head busted off and stuck in the piston before, not sure what killed it.
Lots of these big singles don't like reduced oil flow, I know the NX650 engine went through three iterations of oil pump to try and sort the oil feed problems, the early ones had an 8mm rotor in the pump and the later ones had a 12mm, but the problem is the actual pump body leaking oil when it gets warm.
Especially around the seals.
Funny thing is the US market XR650L has the same engine and never had these issues, they got a pump with a proper seal..

Lot of these old bikes had foibles that if unaddressed could lunch the motor, the big being no exception. The cam, journals and rockers were quiet and pretty fresh on this one with 66k kms up on her.
Principal killers on these are running lean, that seal and excessive crap flange sealant clogging pick up/jets. If you sort that, the bogus cct and spring (head off) and the crank doesn't knock your golden so long as you kill the motor with the decomp to prevent kick back. They're a very understressed lump and plod along forever.
With the ring gap well in spec I didn't change the piston and she was just given a nice rehone and the head skimmed a tad. I hope she should do at least that again before she needs a new one. Time will tell.
What ya working on yourself?

I'm stripping the Montesa 315R engine, taking it slowly. I have already seen that I need a few pieces and parts are taking forever to arrive from anywhere.



Lucky that my NX only has 23k miles on it and I have a replacement Oil Pump to fit from an XRL next, just need a gasket.
Lots of knowledge around for the older lumps now gained through painful experience of owners through common failure modes.
Its a good time to have an older machine with all this info available to hand.
Don't worry I'm not going to chop mine up and make a Café Racer out of it.

Lol of I see another vid of a fella with facial hair bending seat frame rails I will cry:pac:
Whip up some pics of the montesa engine work. Mechanically are they sound, are you righting any factory wrongs, if there any?

Very true on the trickle down wisdom. The major stuff is all hard won fixes encountered day one shared. Thereafter they were tweeked/streamilned etc, case in point the upgrade CCT Spring remanufacture, a German dr guru did that.

Nice you don't need to split the cases for changing the pump on the dommie! Oil pressure is a must;)

are you not going to clean it?

This one was to be my dirty one but then i oiled the throttle cable:(

Nice machine, Looks well.

From the picture posted above regarding fitting a new oil seal..... you may have fitted to Oil Seal the wrong way round....the open side of the seal faces the oil but by the look of it you have the dirt flat side facing this way which is i assume the oil side

Cleaned mine down today.

Snowfoam followed by a shampoo and fallout remover and prepped for a glaze then wax. Then a ride around the back of the airport to a work site and she's covered in flies again!

Ahh now that would explain it, we have a few customers for what are called CK seals which are a back to back oil seal, always in a gearbox use, I work for hydraseals.ie

Your a very handy dude to know so!
As she's an air/oil cooled single and these seals tend to suffer I said I'd try and upgrade to viton.
As it happens I couldn't source the seal in viton in the original size of 16 30 6, but could get her in 7mm. After test fitting there's clearence on the shaft for 7mm so went ahead with it.


In your experience are there any drawbacks or limitations to using viton where buna/nitrile based seals were used as oem? As a material to my untrained eye and hands it feels a less pliable material, is this a concern where a degree of flexibility for sealing is concerned?

dubal2008 wrote: »

The biggest difference is the working temperature range and the overall quality of the materiel used to manufacture it.Whereas an oil seal used in normal application is manufactured in an unknown Chinese Place the branded has certain quality checks and tolerances which have to be matched.
I would have thought the original fitment would have been viton material from factory.

It may have been I'm unsure of what industry standards were required from the late eighties. For some reason I always though viton was a relatively new arrival, almost as a response to ethanol concerns?
Do you guys sell like a pack of viton o rings in standard metric sizes? Say 200 pieces with the major sizes from 5mm up to 15mm?

I ran into problems getting crank seals for the 315R , had to do some digging and found a 25x36x6 Suzuki RG125FUN crank seal fitted one side, the other is a strange size 38x52x10 twin lip Viton.

Cheers Dubal, yer probably right, I like the idea of having a raft of various viton o rings at my disposal. Perhaps an expensive arrangement but may look into it, be a real bonus for the garage like.


Gave her some zap and some juice and glaze my nipples and call me Rita if she didn't just spring into a lovely even quiet idle. Pick up is sweet, and I'd say 90% there. Swapped out the idle jets and leaned her off a touch and she's better again. Choke enrichment off but made up the motor is quiet and smooth and carbs looking good too.

Fitted a speedo cable to a Honda NT650 today

Except it's not finished. It's in the back of the speedo and ran down to the wheel where it should be

Only then I noticed there's no clip to screw in to hold it in place. So I have it cable tied to stop the wire flying around

Anyone know where one would get the holder part for that end that screws into the wheel ?

Cheers

The last one I replaced was moulded on to the end of the cable.
Could you use a P clip to secure it to the hub?
