I guess Honda/Montesa follow the the mantra "If it ain't broke, don't fix it" Unlike some of us that seem to adhere to "If it ain't broke, fix it until it is!" 🙂

That does sound like what we would call a bad earth (grounding problem).

Thank you LSV! appreciate the advice... i have a neighbor up the street who is an old Harley petrol head...an electronics engineer by trade who before retiring used to install the radios and comms for police vehicles. He has said he will help me and take a look. Also i have another problem as the rear tail light blinks when the indicators are on, so there is some of kind of grounding issue going on, be good to get it all sorted - will keep you updated as to the results! all best, johnny

I would have thought a switch in series with the main fuse would suffice as they don't need battery to run ignition I believe. But I stand to be corrected! 🙂

Thankyou

18 quid fae Ebay

My bike does not ping anymore at mid throttle and it revs clean all the way threw the RPM range and over rev I let a Vertigo rider try it He gave it a two thumbs up. It runs like my EFI

Hi Big John! its been a while since your post regarding Dalesman decals so i guess this is a long shot! Do you still have any decals available? Best wishes, Andy

For any one that is interested I just found this that gives the necessary information about the SMART CARB SC2. https://youtu.be/tBuwSkjruk0?feature=shared .

The design of that carb is very interesting I like it a lot but at $700.00 USA and £770.00 in the UK it seems to be a works rider only choice. At club level in the UK it seems a little excessive to my mind . A couple of years ago I bought a second hand genuine KEIHIN PWK28 with standard manufacturer recommended jets/settings for £50.00 off ebay gave it a clean by hand and it worked absolutely crisp from pick up through to rev out. If you have Elons money then of course why not if it works as well as they say its like having fuel injection as you point out. Enjoy and no more jetting problems for you , that has to feel good. All the best Alan.

Remember to get the rims properly drilled for your hubs and spokes. Have a look at for instance Villiers Services homepage Lots of interesting stuff.

Think y´ll be happy with alloy rims and shiny S/S spokes with chromed brass nipples, as per Central Wheel.

I just bought a Smart Carb now it runs like EFI perfect

you can get them here https://www.central-wheel.co.uk/products/classic-rims/stainless-steel-rims.html I have a pair of ss rims on an old greeves.

Not used SS rims on a trials bike just older Road Bikes that I have restored.

Alan, you are a legend mate, thanks for all the info, explains a lot. Half the battle is knowing what the parts are on the EM as the parts list just gives codes that dont come up with anything when you search them. Have just found the Jitsie spacers so i'll grab some and give them a try first.

Thanks for that very informative post Alan. My missus has the '25 Factor-e and the front disc has a very slight noise under rotation. The mud and a bit of wear has shut it up but that explanation is very helpful in understanding the issue. She had a Beta Evo years back and I replaced the disc with a Galfer and it was much better than the Beta OE. The current EM setup is very good though - the braktec stuff is excellent.

Hello there I am back again, glad you like the referenced YouTube suspension stuff. I just messed with a Floating disc recently as it had too much play in it for my liking . About 15 years ago I managed to get some floating disc spacers that a trials enthusiast had made to closer tolerances out of bronze or something similar and they were perfect with sideways movement only so no clunky feel when slamming on the brake to hop the back wheel sideways or clanking noise , sadly these are no longer available. EM is headed by one of the two original French SCORPA founders that parted ways to form EM the other started SHERCO and so with that connection you have EM buying in SHERCO/SCORPA (same owner) swing arms and side stands and other things from the SHERCO/SCORPA PARTS BINS. the front hubs on your EM bike probably carry spanish made NG discs that will fit other makes of trials bikes as the BRAKTEC Front calipers used to compliment them are commonly fitted on most trials bikes as standard and will fit OLLE/R16V forks as they do TECH. With this being the case your EM discs will have floating disc spacers the same as used on the SHERCO/SCORPA and GASGAS bikes. If you want to buy new ones then JITSIE make them to fit but these in my recent experience have a lot of slop and I was using a brand new NG disc so everything new no wear . In the end I bought a NG made fixed disc (will fit straight on most front trials hubs that use a floating disc) that was used on the 2002 GASGAS TXT PRO model and it works great with ZERO slop but of course if you crash and bend the disc you will have problems as the fixed disc has no easy side movement like a floating one. Hope that helps you sort things out. If you do not like the amount of movement in your floating discs then you could try to get some one with a machine shop to make some disc spacers that have a closer tolerance in your discs. Hope that helps now or in the future. Regards Alan.

I haven't heard of trials bike stainless steel rims previously. Where did you source them from?

I’m rebuilding a Beamish Suzuki and going Alloy rims with SS spokes, I’m going to trial it, I’ve done older stuff for show and have used Stainless Rims which are nice and shiny and don’t tend to rust like the chrome option.

Cheers mate, i did wonder. So nothing to worry about then?

That is normal for all bikes. By design, a "floating disc" allows for a bit of side to side movement. With time and wear a disc may not remain perfectly flat and parallel to the caliper and brake pads. The floating movement of the disc is designed to compensate for that.
