Tom, what do you mean a Hydro? i'm not familiar with that term in regards to a motorcycle... can you please explain.
Couple other items to check out: make certain that the fuel line in the gas tank has been replaced with a 'submersible' hose, and that the plastic fuel filter has been replaced with a metal one. And you might want to replace the gas cap with an all metal one from MG Cycle.Bloody ethanol!My '04 EVT is still rolling with well over 200,000km on it.Cheers!G
Welcome to the best replacement for Facebook evar (as someone mentioned earlier today:)Hydro means, this engine is Guzzi's first (and last) attempt at hydraulic lifters. The benefit being you never have to adjust your tappets!!! (or buy valve cover gaskets again )However Guzzi did not do so well with the implementation. Around 25,000 miles the CAM starts to eat itself. Spreads all the metal bits throughout the engine till its dead and done. There were three CAM recalls. The final being the necessary evil to keep the lump going.Checking if the CAM recall is pretty easy. First, pull a valve cover off. Check the rocker arms for adjusters with a sheared off surface. Pic here http://wildguzzi.com/forum/index.php?topic=45144.msg677444#msg677444. Then check that the valve spring caps are not magnetic. If these checks turn up good, good chance the recall work has been done. However as I just found out with my 03 EV Touring, sometimes the recall wasn't completed fully. In my case, the tappets and buckets were not replaced with the recall parts and the recall CAM has now started to eat itself into bits So I would take your recall step one (or two or three) steps further. Step one would be drop the sump, then peer up into the crankcase from down below. If the CAM has oil holes at the bottom of the lobe, its the new CAM. Old CAM didn't have em. Also check that the DLC (Diamond Like Coating) is still intact on the bottom of the tappet buckets. Step two is for the semi-ultimate assurance that your block will go the miles. Take the valve covers off (hopefully they are still off:), then remove one or both rockers. Remove the pushrods (making sure to label the top of the pushrod and the side it will go back in). Take a small magnetic pickup tool with long reach to remove the hydraulic tappet. If the tappet DOES NOT have a flimsy tin foil hat that holds the plunger in BUT has a circlip, the tappets were done too. Step three is for the true paranoic: that is to check the oil pump for damage. If the CAM started to go, the metal bits go into the oil pump as its pre-filter. You'll need to pull the timing cover, remove the timing gears and chain, then remove the oil pump (which is a most hateful experience). Neat part is while your in there you can put a valtech timing tensioner in there (http://www.mgcycle.com/index.php?main_page=product_info&cPath=68_126&products_id=347) and a higher output CNC oil pump (http://www.mgcycle.com/index.php?main_page=product_info&cPath=68_162&products_id=1985). Make sure you pre-fit the key into the oil pump sprocket key way. My pump's key way was too small, thus I had to remove the pump to dremel out the key way to fit. The oil pump is really no fun to remove. Even with heat its a PITA.This concludes checking for the CAM recall. Hope that your block is good to go, because the pickup of that dang hydro is intoxicating Have no fear if your hydro hasn't had the recall work. Mike Haven of now-defunct-MPH Cycles has a few kits left and is willing to loan out the tools for a refundable fee (or someone on here will lend em to yah)But wait there are more things to check.Another sore spot of the hydros was a single plate clutch that failed rapidly. Single plate clutch was replaced with the standard dual plate clutch. Easy to check. On the RH side of the engine there is a timing inspection hole in the bellhousing. Take the cover off. Peer inside. If you see lots of flywheel to the right of the ring gear, your got double plate clutch. Here is a pic http://wildguzzi.com/forum/index.php?topic=60644.msg926522#msg926522Lastly, certain castings of the triple trees were known to crack. This was a goverment issued recall. Easiest inspection of them all. Just check the trees for cracking. You can also check your casting number against those that were found to fail here http://wildguzzi.com/forum/index.php?topic=45144.msg677398#msg677398. If none, ride on into the sunset pilgrim.Hope that your checks prove a sorted hyrdo.
So this will be your first Guzzi. I'm curious to know what your first impressions are. I bought my first Guzzi (a V50) without a test ride and when I rode it home I thought it felt like a plank of wood. I came to love it.
Pls correct me if I'm wrong, but it is my understanding that the valve/cam issue with the HYDROS was NOT a recall but a technical service bulletin and will not show up on recall records, so saying all recalls were done doesn't necessarily mean the lifter issue was resolved. If it was a RECALL the mothership would still be on the hook for the recall work forever and a day such as the triple tree issue. The work if done will also not necessarily show up on Guzzi records as well. Just so the purchaser goes in with the correct info and his eyes wide open.Hope all is good, Tim
Hydraulic liters , from the factory there was a major issue with these . A quick search on WG will clue you in . Good luck and welcome to the family . Dusty
It should contain hydraulic lifters (which negate the need for periodic valve adjustments).Unfortunately like 99% of the rest of the world Guzzi screwed the pooch on something with design or parts specs on the hydro motors and they were likely to fail early. Guzzi worked through 2-3 different fixes until they finally hit upon THE ONE.Hopefully it was done as those kits are getting scarce. The only real way to tell if it was done is to remove the valve covers and see if the valve lash adjusters were broken off (last step of the correct fix)In theory a dealer could run the VIN against the Piaggio NA database, but sadly it was reported that some dealers submitted warranty claims on bikes that never got the fix, therefore that method would be unreliable.I'm told that once the proper fix was in place that they are stellar motors and should give you years of hassle-free enjoyment.
