I know this question has been asked, but will the internals and the top adjuster from a 748 fit in my std showa forks? I would like some adjustment on the front end without changing/modifying the front end too much.
The two forks could be the same internally.... but then again they might not. Normally forks built with no external adjustments have some cavities inside the fork tube which allow the emulators to bleed under high pressure loadings, normal forks with adjusters are built with bypass shims in the fork stack. Also thread pitches could be different in the end caps. Only the manufacturer could tell you this information or someone who has done the conversion. Try to speak to a couple of quality suspension experts to see.

People have fitted the internals of SBK forks into SS ones so should be able to google and find some info
Yes/no. They will screw in and do nothing positive at all without major internal changes. Change the forks.
Thanks for that all, might leave alone for now, I'll speak to MCT as their only a mile from me and see what they say.
Tbh unless you need loads of adjustment regularly, travk days racing etc, getting them rebuilt properly is more than sufficient.
Lumbux, I spoke to MCT about mine, and to fully rebuild, change them with a full service and their own 20mm cartridge kit is £350 + vat, it is on my to do list, they state this will transform the handling , BUT they recommend that you do at least the same to the rear end or buy another aftermarket shock (which I did).
Not sure Al, their non adjustable, but they have had a full service with new seals so no point fiddling the more I think about it. Got other problems to sort now, I think a wheel bearing has gone in the back wheel! Always somthing to do.
I can lend you a serviceable rear wheel with disc and tyre if it helps.........and I may have a bearing or two (used, but OK)....also have a spare sprocket carrier with good bearings and a sprocket. Regarding your forks, if I were you I would leave them on, because they are better than the Marzocchis, and quite frankly, when I fitted my adjustable Showas which I had sorted by MCT, they weren't much of an improvement over my Marzocchis which had also been serviced. You can borrow the Marzocchis as well if you want to play with yours...
Al, interested did they service or did they also do the cartridge update ? Don't want to spunk £420 for no discernible improvement
Thanks mate, just looked everything over, no play but it creaks every turn, so I'm guessing that a bearing is on the way, need the bike Monday so will be a job for next week. I'll have a look at the forks I'm sure their showas, but I could be wrong!!
Had exactly the same and found the spacer was too long so the bearing wasn't seated and causing the bearing to turn in the housing (wheel was scrapped in the end)............but equally, the spacer could be too short and your bearings are being compressed to get them to touch the spacer........try slackening the axle a bit and see if it still does it.
Stripped, new slider seals; new slider and guide bushes (which I think are the wrong size); oil; I wouldn't call it a cartridge as I understand them, but a cylinder with a valve in.................re-valved; initial settings done.........No further advice or assistance forthcoming afterwards (I suppose that comes at an additional cost)...... ........Not overly impressed with results, for the cost involved.
Change the oil, set the air gap, springs for your weight and for most thats 90% there and 100% better. Once you have had them apart, uou can see how easy it is and if you want more/less preload you can easy adjust with hoke made spacers. Plumbers pipe works a treat
Bradders is correct, but the adjustable Showas can be a bit of a bugger to get apart, especially if the slider / guide bushes are a bit worn as they can get jammed when pulling the slider out. Also, when dismantling, back off the adjusters completely (to their minimum settings). In addition, when dismantling, unless you have a suitable tool, you will probably need someone to help; depending on which way you dismantle them.
Yep and the Marzocchis are easy as well............ I think (and I mean think) there are two ways to get the Showa adjustables apart...... .....One is struggle to compress the spring when the top cap is undone, so you can get the top cap completely off.......Some people do it with a proper tool, others use two screwdrivers and some use a homemade tool which means you can do them on your own.....(like I did). .....the other way (which I haven't done) is to remove the bolt from underneath the fork legs............I don't know if that avoids the slider / guide bushes jamming.
Rear wheel bearing is just on the way, so will replace all 4 as its in bits and hope that's the problem.
